I've done something similar (Fencing instead of Swords, Med instead of Focus), and it's pretty fun to run with, and enough Chiv (60, Tactics and Eval only GM, rest made up with items) to get a Divine Fury off if/when needed (for stamina).

The best armor for +MR normally ends up being mage armor (or leather) any ways so Focus isn't entirely needed (if you go with Chiv). I kept my Dex at the right level I needed that when Blessed I was at 85+ (in case cursed).
