makers cult might've already done what you're looking for. didn't like them much at first, then I saw a whole feudal guard army painted and slowly shifted over. now I'm so used to their kinda "chunky" marine design normal ones feel off somehow. also they've been doing death corps right from the start, so you know they have good taste.
anvil does digital too now, some might already know them since they sell physical units as well.
only thing I haven't found an alternate for are sisters, OPR has some but they didn't really WoW me. raging heroes has damn fine ones (crimson redeemers), but only in resin (and they apparently said they have no plan to sell STLs of their existing lines and they mostly do fantasy - although they did
eldar last year so, who knows).
mainly play it coop if I don't want to get into sweaty competitions. can't wait for 5 leagues, always preferred fantasy more for that, and might finally be able to play rangers of shadow deep too.
also could've sworn there was a necromunda alternate floating around, but can't find it right now. or I'm confusing it with 5core/5hammer...
maybe one of those works:
