Fortnite, COD, Warframe, Halo all have it. Many other MMOs do. Maybe I'm wrong, but it seems like you're falling behind the times to me. Hardware support is available on both consoles, and you've already worked it out for the game on PC. I don't think it's a "can you do it?", I think it's a question of "will you?" And if you won't, why not?
Controllers get a boost in aim assist do to them having slower turning/aiming cause on mnk you can do 360s twice the speed that a controller can. So if they did do it, mnk on console would get that aim assist, so they would them have to make sure the game can differentiate between mnk and controller.
Some people are actually using modded mnk inserts for console to make it look like a controller giving those people a massive advantage. So if it became a thing lots of people would abuse that hack to have an insane advantage.
