When your characters ask you to realign your thinking ... that's what you do!  Regardless of how much time it takes, or what a pain in the patootie it might be.  The most important thing is to be true to your story and make your characters as good as they can be.  Character development is everything, imho.  Take the time to get to know them yourself, and take the time to put all those details in.  And as has already been said, your alpha character doesn't have to be the narrator. 

Good luck, and have fun!  :)
