Short answer to thread question: No. It will not.

Extended:
I think the Keepers of the Moon have the highest Mind stat, however, at the end with a relic, that may only result in +9 more healing out of a 620-680 HP heal.

But you'll have slightly lower HP (up to 90 HP) out of say 2800-3400 HP (gear, party bonus, stat allocation). Both, to me, are minor enough that aesthetics take greater precedence over the minor stat exchanges.
