I imagine that they are limited by the die cut though to the shape of a lego fig. Would that shape work on a Kreon? I'm guessing that the upper corners of the chest by the shoulders would go uncovered. (just noticed the other sets like shields and the like so maybe they can do other die cuts)
I'm guessing that BF is lego only?
Eye-balling it by placing two torsos next to each other, Lego is slightly more narrow at the top and wider at the hips...it is also a slightly longer torso.
The BF stickers wouldn't quite fit squarely on a Kreon...but most of the images that Hasbro stamps on a Kreon torso don't fill the whole space anyway. (And most of the ones I've bought weren't even stamped on evenly.)
But, of course, most of the accessories and extra-bits that BF sells would be hand for extra robot parts. They would be quite handy for expanding an arsenal.
UPDATED:
I don't see why you couldn't pitch your parts to Brickforge. After all, the legs and arms are just as Lego-compatible. The only issue would probably be intellectual property rights. I don't know if they would give you a cut or merely buy the rights to the parts from you or what. They might want to stick to their own original inventory to avoid legal entanglements. You can always make a pitch, though.
