Personally, I would like some more “diegetic” heads and skins. Kinda like the heads in the Borderlands remaster: they aren’t that outlandish, they look like things the characters might have actually picked up and accessorized with.
For example, Fl4k could casually wear the masks/helmets of their murdered victims as portable trophies.
I’m talking lance assassin helmets, forerunner heads, guardian heads, saurian skulls, jabber fur scarfs, COV masks, stickers like V3R0N1C4’s ones etc.
I wonder if they’ll go a bit in the direction of Battleborn, by having different “tiers” of skins (with simpler ones which only change the colors and patterns of the characters’ clothes, and the more complex ones actually changing the model).
Maybe they could also recycle some of the scrapped customization ideas from previous entries in the series:
P.S. I know that not all of these were scrapped, but most of them were.
