Presumably this would be 11 pounds on top of the existing load out, in which case 11 extra pounds wouldn't be a trivial amount. Probably subjective though.

Not if the rest of the loadout is on a fully powered weight bearing exoskeleton.

In that case this system would have to be much more than 11 pounds to have enough fuel and thrust for the added weight.

If it's self-supporting, it can weigh more because you're not limited by what the soldier can carry.
