Letting attack-limited evade buffs bypass the cap sounds like a good idea, but it would only worsen the issue of balance being made so difficult due to the disparity between optimized and unoptimized builds.

Really, I think that only your highest hit and/or evade buff should factor into accuracy. But if that's not going to happen, making the attack-limited buffs into 3-turn effects with a lower effectiveness should be fine.
