I'd take accessory sets if the time and effort on them were both right...
I'd dig some sabers/hilts... Multiple "EU" colors would be nice too.
I'd dig it if they tossed in some either new weapons... Shoulder-launchers for Clones, grappling hooks, packs w/working straps, "cargo containers" like the Scanner tech's, the MicroMachines mousedroid, etc... Lots of really ideal things they could tuck into those sets.
The thought of an interchangeble pauldron for Commtech and VOTC STormtroopers would be neat...
If they packed an army builder in (a good one) I think the old Target concept of accessory sets would be superior to just putting a bunch of weapons in a package. Pack a good battledroid, Clonetrooper, or Stormtrooper in and it's like gold to most people... God knows they've got the GOOD figures around now to do that, what with the Clone Commander, C1 Clone, VOTC Stormtrooper and such. Be interesting to see anyway...
I could see those becoming annoying to even try and find really, if those were the figures being put in them.
