If your collection is in GOG or itch.io, yes you can do that. But I don’t think there’s a good practical way to do it with Steam games.
Jc141 does compress games in a wine wrapper for ready use on Linux using dwarFS. I could see those working for this is it’s a steam only release. So if you put in the work yourself to do something similar then maybe so. I think must be including Goldberg emulator or something in there to keep them running without steam.
