I think it's great that you intend to take on lead vocals: people want to hear you sing. But you should put in some work in it because you're going to get criticized, and we all know how much you hate that. This means that you must be singing all the time, not just when you have a guitar in your hands.
Vocal harmonies are more powerful than vocals in unison. Vocal harmonies need to be rehearsed. With your Hodge Podge politics, the only ones who are present for every gig are you, Prince and Brandon. So you three are the ones who must carry all the vocals. Why loyalty? Because people hear vocals first. Build your band around people who are loyal. You will sound the best that way. Of course you could rehearse harmonies with hired guns, maybe you could get the same results as the Beatles. Maybe.
