Very unlikely to happen via emulation, there's Switch 1 games that the Steam Deck struggles to run already.
More likely to happen via recompilation, if anything. Game ports via recompilation have been taking off in the last month or so, all the way up to systems as recent as the PS5 and Switch 1. It has far less overhead than emulation.
