These are customs, but if the next wave is Fin Fang Foom BAF, this might give us an idea how it looks -

The guy gives the recipes for them too I think. Anyway their not bad, but if that was the actual line I'm not so sure I'd buy that line. Not that he didn't do a great job, just read the recipes. Tho I do admit the Superskrull and Silver Samuri would be nice.
Personally I'd want -
Tri-Sentinel series (had trouble of thinking of a large foe for a sec, but he'd fit the new 10 figure BAF thing they got going now.)
Emma Frost /w. Upper Torso of Tri-Sentinel. Also Diamond variant.
Thanos /w. Upper right arm.
Cannonball /w. Middle right arm. Also with blasting off feature, possibly remove lower legs and replace with that.
Hercules /w. Lower right arm. (they always seem to add someone more b-listish, tho he's not a bad character or anything.)
Exodus /w. Upper left arm. (Always wanted an Exodus from X-men figure.)
Avalanche /w. Middle left arm. Also a few rocks, or brocken rocks base or something.
Gladiator /w. Lower left arm.
Cloak & Dagger w/. Lower torso. Have the Dagger figure, and because of space for the Lower torso, simply have Cloak as a skulpted head attached to a cloak or something. (This fills another semi-obscure spot, and adds a second woman to the line.)
U.S. Agent /w. Right leg.
Silver Samurai /w. Left Leg. Of course comes with a sword.
