Which way should we spell it?

Ok, so we have a 5 year old named Mia. We have FINALLY decided on a name we all like for her sister! So we want to name her Amy but I want to spell it Ami because I think it would be neat to use the same letters as Mia. Is it “a little much”? My husband isn’t against it but just isn’t 100% sold on it. What do you think?
