How about taking nuts and putting a quicklink on the wire, with a flexible dogbone and biner, making them similiar to racked cams (that have their own biners).
I know every one else has beaten you up about everything else in your post, but I've got to respond to this part (for some reason?!?).
Peguet, the maker of Mallion Rapide-brand quicklinks, makes a Zink/aluminum alloy quicklink (they call "Zicral") in two sizes. 7mm, which has a breaking load of ~12kN and weighs a scant 18 grams (less than a CAMP Nano!); and a 10mm which has a BL of ~24kN at almost 49 grams (about the weight of a bigger non-locker).
Most nuts have a strength rating of 10-12kN and most placements in rock will only hold ~10kN max anyway, so let's go for the 7mm quicklinks.
14 quicklinks (for 14 nuts) with 7mm quicklinks = 8.8 oz.
14 Nano biners (@23 grams each) = 11.3 oz.
Two and a half ounces saved. I say go for it!
