What we did for the community tortle (which will come out next update) was to catch the DEX modifier and subtract it when unarmored, if armored, we set any worn armor bonuses to 0. This leaves shields and magic bracers/rings alone as is indicated by the tortle. It's not beautiful, but it works. It also allows a tortle to wear armor of resistance and get the resistance granted, but not the AC.
