Whiskeykid,
You could try the "slippery overhand knot" to backup the pigs with the hauline.
Basically it is a series of overhands where you just pull half a bight through and repeat (sorry hard to explain), it's the common way contractors coil up extension chords.
This knot if pulled from below by the pig will tighten, but if pulled from above will come undone. I'm not %100 sure how you tie it to the anchor.
PTPP posted a photo for his solo-tag thread:
Worth a try. Careful out there.

Thanks for the suggestion! I read about that in Chongo but forgot entirely about it. I'll give it a read when I get home.

Yea, thats a heck of a lot easier than fabricating a gidget. I think it works because someone (PTPP) uses it. Think I'll give it a try.

My dumb comment:
1. I have a silent partner I sort of hate (prefer gri-gri for solo aid).
2. Falling pig should be plenty to deploy it.
3. So couldn't one with a spare silent partner thread ~20-30' of spare cord through a silent partner back at the nachor as a backup?
Hauling:
Haul as usual, movement is too slow to trigger silent partner, life is good.
Falling:
Pig factor 1's onto anchor after a few feet, though hopefully it's only ~100-150 lbs, so most big wall anchors should be able to handle it.
So other than having to carry a 1 lb silent partner, and another 1 pound of rope, what's the downside?

Moof that was brilliant!
The 20-30" for extra line I'm thinking will feed out till it runs out. Then it pulls through the SP.and off your body hauling like normal.
Rather than an extra rope, why not make a longer tail offthe haul line?
Lets supose Lambone takes a whipper ;-) and pulls the pig off its hook, pig begins to fall, then locks. Wouldn't begining to haul unlock it?
No because the drum still wants to pay out the same direction.
Conclusion;
This would work, but if you fall on that pitch, know that you can't body haul that time. YOu'd have to rap to the anchor, lower out the pig, clean, and haul just like every one else.

I can like dig it man.

some ropes course giant swings use a quick release so the participant can be hauled up by the group as high as they want to go, then they pull a cord, a gadget opens up and they swing. it could probably be used for the haulbag too, you'd just need a long piece of cord to activate it.

The only problem I see is if your pitchs are not plumb. As the pig lifts off the hook they will want to swing, they could swing out away so fast that the SP locks, and your back to square 1.
Sorry to rain on your bursting bubble.
Still need a reliable remote lower out, and then it would work.
What if you pre lowered out? That means your pig is dangeling 20 " below the anchor. Thats a long tether on your Fifi.....
Hmmm more thought needed.

Indeed, if the swing is big, the SP could bugger things. However, If the swing is big, I'm not sure I'd want the bag swinging. Further, the counter weight haul is only useful if the belays are more or less inline with eachother, as otherwise getting back to the lower belay at the bottom becomes problematic at best.
If the SP did lock, it is not the end of the world either. At worst you might have to jumar to the station and let some slack out to allow rapping of the haul line, or jumar back up and rap the lead line (which is a PITA, and if done poorly can result in gear getting out of reach). The bag would hang on the SP with the haul line backing it up in case it slipped. A PITA for sure, but not dangerous, and not something you would have to deal with repeatedly, only on a fluke.
I gotta give this a try...

EXPERIMENTAL and Dangerous!!!
How about auto-release docking with a KONG gigi?
Hauline is tied directly into the hole at the top of the gigi.
Haulbag locker is clipped into the bottom hole of the gigi.
Pass the ends of a doubled 8' length of 10.5-11mm cord through each of the long slots, so they go around the spine on the back of the gigi and out towards the front/flat side of the gigi.
Equalize the length of the tails and put a narrow strip of duct tape around the ropes close to the flatside of the gigi to prevent losing the cord.
Thread the two free ends back back through the flat side of the gigi and on top of the bight/loop of rope. You now have two loops of rope that you clip into the haulbag anchor powerpoint locker.
It is important the gigi is pulling straight down and taking the full weight of the haulbag and that the tail ends of the rope are equal. If the direction and application of force isn't just right, things will get real dicey in a hurry. Take back-up precautions while setting this up!!!
I think I would use this docking method in conjunction with the 2 taped together Petzl fifi hooks.
Unlike other systems though, the fifis would not take the whole weight. The gigi must bear the entire load. But I would have the fifi on the haul line hooked on a carabiner above and in alignment with the gigi and have a thin bungee cord Prusik on the hauline below the fifis to put slight tension on the fifi hooks while keeping the gigi weighted. Above the fifi would be the Prusik on the haul line as normal connected to the maillon rapide in the slots of the fifis.
When you haul, the fifi comes out of it's carabiner and the gigi docking tether releases automatically.
Probably best not to use the haulbag as a belay counterweight in this situation. Also this configuration makes it cumbersome to incorporate a swivel, but then the use of the fifi method should be selective (for use on straighter lines). Use only with relatively light/grade 4-5 loads.
If another party bumps your load, all bets could be off.
