Is there even anything that would make sense? A lot of the older enhancements were because of the limited compute ability of older consoles, or adding sensors like the already mentioned gyro sensors and light sensors in GBA games. The Switch is already more powerful than anything you could reasonably add in a cart, and probably already has any sensors you'd reasonably add too. If there's anything else that could be done, that'd be interesting to find out.
