best that could be done is a PC game.
Online gameplay on real SNES systems is definitely possible.
I mean, the X-band did a similar thing back in the day.
I don't know about the limitations of SMW itself, but according to what the dev said, every player would be able to play the game in full-screen on his respective console together over the internet.
Maybe, it would be worth a shot to ask him about it, I dunno.
