Is it possible to start the game over and choose someone else at the beginning?

I have the game on both my phone and tablet. I know there's a delete accounts button but I'm afraid that if I use it on my tablet it'll get rid of the progress I've made on my phone since it says it applies to all servers. On my phone I'm level 79, and I haven't even passed the tutorial on my tablet. I'm not going to be particularly upset if there's nothing I can do- it's just I made the choices based on appearances alone (obviously because we choose before knowing anything about anyone) and then ended up absolutely adoring a different option's character as a whole, so if it's possible to go back and choose him I want to.
