Sounds cool in theory unitl you realize
Switch 2 is a custom Nvidia ARM APU with a custom software stack
While arm on Linux exists you run into some issues that could kill performance.
X86 to ARM Translation is slow and power inefficient, While Valve is working on FEX for the steam frame even devs that have it says you lose about 20-30% of CPU performance if not more of the performance in games. Your better hope the things you want to do have an existing ARM build thats really good. This is also not accounting for any additional overhead added by Proton for non native linux games.
You also run the 2nd issue, Reverese engineering and reimplementing a custom driver stack for the hodge podge of a GPU nvidia stuffed in the switch 2,
