I say "easily" because it wouldn't require a major effort on the scale of coreutils. It could just be a series of fancy automation scripts. It'll take effort, but not the most intense of exercises.
I made a handful of them at an old job because we had a few specific tasks that we would regularly do, but not enough to commit it to memory. I just spent an afternoon here and there slapping together python scripts with just the options we would need and tossed it into /bin
As long as you're cool being a bit more restricted in multiplayer games (a lot work great! But some developers are blocking linux), and you're okay with AMD (nvidia is improving though), gaming is basically on par with Windows at this point.
In some cases it's even better. I have a few games that require weird tricks to get it to work under Windows, but work fine in proton. Even Elden Ring at launch ran better on linux because it didn't have the micro-stutter issue.
