Given the way might works, if you want blessings to matter but not being engines that drive exalts to total superiority, it might make sense to add in blessing bonuses after the Might multipliers. For mortal troops, the strong favor of a god is a game changer, the way you have it a vastly more powerful for exalts, instead of a nice bonus.
Having it before might multipliers should be a special power for dedicated holy armies, champions, avatars and such. If we get a white wolves unit for example, or had the priest as a hero.
