It's possible... but there are risks in going that way. Fragmenting your fanbase is a tricky thing. We didn't see very many "New" 3DS games that were successful. Similarly, only a few Game Boy Color games outside of Pokemon were really big. And even Wii games with Motion Plus were hampered by hardware fragmentation.
Unless they've solved this problem, I don't know if that's a good idea. If they can effectively boost the switch through a dock, that may be a way to do it, but as I understand, that's not possible with the hardware.
