Valve would be unbelievably better off just opening up Steam OS as a legitimate free distro, as opposed to today's trying to shoehorn the custom Steam Deck OS onto other hardware.
If they did that, and Valve came to an agreement with MS for native GamePass functionality I'd probably throw that on my ROG Ally in a second.
There are distros using the deck restoration image. I'd say it's basically steamos... But then why haven't valve released it themselves? There's something going on there.
As for game pass, I think there may be a level of integration with windows or the store backend that would make it non-trivial. Not sure, though.
