It wouldn't take much to make one Warpath that could be Liefeld or Capullo - two sets of armbands, chests, belts, and hair - and then the set would be a clean 50/50 split between the two eras. Feral's Capullo costume is also a pink bathing suit, but it's a completely different design from the Liefeld version.

Grandmaster has silver hair that's appropriately poofy for 80's Atom. It's got pink ears, though.

Blue Marvel, right?

Fang/Wolverine/X-23 is what came to my mind.

Did Cyclops ever wear a jacket with this costume? I know an old ToyBiz figure had that combination, but did it show up anywhere else?

You drew for West End Games' Star Wars RPG, then? That's really cool, I love their books.

Barbarian Hulk is the best match I've found.

Other Shi'ar/X-Men characters like Fang Wolverine, Polaris, Eric the Red, or Deathbird could take those last two spots, too.

I'd rather one of the later Roger Stern lineups. You could still have Jan and/or Jen, but with less rehashes and lots of characters with recently-raised profiles.

That'd be a lot of alternative parts, and unless she also had a Clint head it wouldn't really be a new character. Maybe it could be D-Man?

If Hulkling's chest cover uses standard wing pegs, it'd be perfect for a classic Mimic.

I think Sunspot came with them in yellow.

Maybe not very ambitious, but I could see a Murphy and Robocop (with battle-damaged parts) two-pack, with Vinimates of Robocop, damaged Robocop, and roughly MM-scale ED-209.

I think Ryu, Ken, and lightly-modified Thunderbird hair would get you most of the way to Shang-Chi. I can think of two more sets worth of "must-have" Cobras, and the eighth figure is Cobra Commander Fred, which might be stretching things. I think the line will get to to army builders sooner rather than later. I know as an obscure driver, Thrasher's never going to happen, and even Road Pig's not terribly likely, but they've got my favourite designs of any Joe characters.

Zartan seems pretty certain, and maybe Firefly and Bludd? Probably not Road Pig and Thrasher, unfortunately.
