Can anyone think of a reason why SWM would not work in a wild west/weird west flavor with (practically) zero hacking?

Can anyone think of a reason why SWM would not work in a wild west/weird west flavor with (practically) zero hacking? And would you play it with me?

The only potential issue that comes to mind is gunplay over swordplay in the Perilous phase, but it seems like that could be overcome pretty easily.
