I think that it is very doable.
Sting'em is right at 15 lbs. , but ttatt has been as low as 14 and change.
If they tweaked ttatt down to 12 pounds, then later converted it to a drum bot, the drum would be unreal...it could weigh well over 6 pounds.
we could save 1/2 pound just on the battery pack, in that the powered wedge draws nothing compared to a drum
