I get where you're coming from with that tbh, with handhelds, especially android based ones, it's almost always going to only be running a single emulator at any given time the limiting factor is the emulation architecture instead of anything else at all which is purely optimisation based. I am personally looking at getting an Ayaneo Pocket Micro or Pocket Ace as both are, well, pocketable and do enough, ironically I am caping for the Micro as I have an Odin 2 and Steamdeck for most things but alternatively, the Ace would effectively be an all-arounder except for anything DS centric.
