Ok I need help with a name dilemma

We all have B NAMES me and hubby, our two,boys Benjamin and Brody. I CANNOT decide on any more B names for a boy. I hate all of them trust me I've searched. If we have a girl I have a name Brielle. But for a boy i,just hate all the names. Would it be bad to break our B thing we have going and pick,a different letter? There are so many cute names out there, I mean the baby calls us mom and dad anyways he'll only notice his brothers have B NAMES is it a big deal to go for Noah or something else?
