(no subject)

So Patrick and I occasionally get to talking about RPG crossovers we'd like to see, especially in the vein of "type of story + system you would NEVER expect to see it in".

His personal favorite is a zombie game in Star Trek. Do phasers work on them? What happens when you can't access the sick bay because it's been overrun? When you can't land on a planet because it's been overrun?

But when he asked me this last time through, I suggested "a D&D Western".

( Now, in theory, it's possible to do such a game. )

So I open it to you: what is the best way of dealing with these changes? Should we just leave the classes be, in the event that we ever run such a game? Or should we allow our players to substitute in other feats for Armor feats? What, if anything, might be done to tweak the races?

Comments of "don't play Westerns in D&D" will be ignored, since that ignores the purpose of the exercise.
