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.

Even coming from a novel, Drizzt is probably the most well-known D&D character, so it would be weird to skip over him. I think he was the only D&D action figure Hasbro bothered to make despite owning the brand.

The diver from Creature From The Black Lagoon, maybe? One of the Khans might work too, depending on the skin tone.

I've had a few problems with hip joints twisting off, mostly on middle-period minimates with cheaper-feeling plastic, but it's happened occasionally with newer items too.

That's fair enough, I hadn't realised they were only drivers. It'd still be cool to see Road Pig, although I imagine other Dreadnoks would come first.

How obscure or unlikely-to-be made are Road Pig, Thrasher, and Wil Bill? I'm not familiar with the characters, but the first two would make great Fallout/Mad Max wastelanders, and Bill looks like he'd be a headswap away from Robert Duvall's character in Apocalypse Now.

I've seen the Transformers box set at GameStop a few times now, but I'd never seen anything before that.

I'd go with Korvac, Vision, orange shoulderpads Wasp, Jocasta, and Stakar, with the sixth slot for another Guardian. Yondu for movie recognisability or Vance for Cap-similarity (and Justice potential) would both make sense.

Any chance of comic-based tie-ins, like the last Spidey movie got? Or is the next comic wave after the F4 too far off for that to be a consideration?

A Korvac Saga wave would be pretty great. I'm not sure whether I'd want it to start an incomplete Guardians lineup, though, or just stick to filling classic Avengers holes.

I've got no interest in the new Spider-Man movie, but I'd buy Raimi versions of Peter, Goblin, and Ock. Without Walgreens, though, either seem unlikely. When was the last time there was a Marvel movie set at comic shops?
