Sure, but the obvious counterargument is that the answer is to eliminate the DH everywhere. I'd far prefer that. I think it should matter whether your pitchers can hit or not. I mean, why don't we suddenly start DHing for catchers? Most of them aren't good hitters either.
Over-specialization is part of what made football tedious and unwatchable and it's doing the same to baseball.
I don't think pitchers focusing and building their careers on pitching at an elite level and hitters having the same focus on hitting equates to overspecialization that's to the detriment of the sport. The parade of relievers comes closer to the tedium factor, and I think putting a timer on pitching substitutions may be an idea worth kicking around.
