Adding the gri gri seems like a pretty good idea, but would you ever just put a prussik above the jugs and let them push it up as you go? Would that even work or would the prussik just get entangled in the jugs?
There is a rather easy method of ascending with a GriGri that can be done on one rope or two (two if the top anchor allows the rope to move through). This method uses a Cinch or GriGri with one ascender, a sling or PAS as a backup, a foot strap and a Mini-Traction.

Basically you step on the foot strap and pull down on the free end of the rope simultaneously to feel slack in. Then you push the ascender back up and repeat. Its redundancy comes from the ascender if the GriGri were to slip. You can use a pulley instead of the Mini-Traxion but I use the Traxion as it provides even more redundancy for the locking cam generally engages if the rope starts to slip through too fast. If you decide you want to rap the fixed line, all you need to do is disconnect the ascender and you’re ready to go.
Edit: Yes I know backup is a compound word.
I hope you never become an instructor cause there will a triage of dead climbers rolling out of your class.
