The second one I love, except I can't tell what the thing with robot-spider legs would actually look like, minor detail. So 95% love. Your theories for giving Jason the benefit of the doubt are great. I just think he's entitled to a few tenths of a second for a "WTF?!?" moment before he goes into action.
The third one is only 75% love, because Bruce and Tim have chins that are a little on the small/weak side. But everyone has great hair, and Jason(?) has a pouty mouth for bonus points in retro's book.
