What do you think of this twinset?

B/B- Tate and Harper  G/G- Irah and Avril(Irah is prounounced Eye-Rah)  B/G- Avril and Harper I have chosen Harper as a boys name because that is my grandfathers name, and he has pretty much raised me, despite the fact that he had to leave retirement to do so. This is the least I can do.
