Wouldn't be surprised to see a set with Spidey, Blade, and Morbius. Maybe a chance to finally get a wide-release Symbiote Suit?

Not even close to perfect, but the best one I can think of is this one from Terabyte. Kinda captures the lime green face

That works as well, but it's a little bit too organic-looking for my preferences. Definitely the third-best option though.

The best torso I've seen is either Killmonger's (Golden Jaguar suit) or this one from Ninjago.

I've seen both the Kylo Ren and V-Wing pilot heads used effectively.

The CMF Arctic Explorer has red legs with dark blue boots. I think that's as good as you can get

Here's an idea for Kang I worked up a long time ago. Purple motorcycle helmet, Airjitzu Jay head, any Power Suit Lex Luthor torso, and TLBM Catwoman legs.

My huge (mostly-purist) Phase 4 figs! Top Row (Movie Figs): Black Widow (non-purist wristbands), Red Guardian, Taskmaster, Thena, Ikaris, Shang-Chi (non-purist wristbands), Mandarin, Doctor Strange, Nightmare, Scarlet Witch, Valkyrie, Thor, Mighty Thor Bottom Row (Disney+ Show Figs): Winter Soldier, Captain America (Falcon), Zemo, Scarlet Witch, Vision, Loki (non-purist staff), Captain America (Peggy Carter), Hawkeye, Kate Bishop

I did a DoFP-inspired one with Hank Pym Ant-Man's torso/legs, red arms, blue hands, Airjitzu Jay's head, Winter Soldier's hair in black, and a blue crowbar for the tail.

I think the Fox Girl's accessories are a reference to an old riddle. "You need to get a fox, chicken, and bag of grain across a river. Only one of those three will fit in the boat with you. However, you can't leave the chicken with the grain, and you can't leave the fox with the chicken. What do you do?" It's either a cheeky reference by LEGO, or I'm thinking too deeply into this.

There's plenty of figs with plain flesh arms. The full list is here.

Nope. Any modification of parts is not purist. What specifically do you want to change? I might be able to find some suitable options.

The Russo Bros said the spoiler ban lifts Monday. It's probably a good idea to wait until then.

Well, now we know why there are so many Outriders in the Endgame sets.
