Feat similar to Practiced Spellcaster, but for BAB?

The problem with this is that it allows for broken gishes. I know it might not occur at first, but the melee classes, the ones that need all of the help, will little to no use out of this feat, where as casters, and, gishes in particular, suddenly have iteratives that normally only the melee classes had. Then again, Divine Power is already a Cleric spell.

I just don't see this being a necessary feat. Other classes a BAB-primary might multiclass into will also serve to promote the overall BAB. Spellcasting isn't helped by any multiclass, so the need the practiced spellcaster feat fills doesn't exist for BAB.
