twin b/g names

Tomasek

I am 25 weeks with b/g twins. We are keeping the names we decide on secret from friends and family but I need help because everyone is saying they need to match/sound good together. We are pretty set on Halle/Hallie Jo for the girl and my husband loves Miles Joseph for the boy. We also like Parker Joseph. (Joseph is hubby's middle name) My middle name is Mackenzie but I just don't think Halle Mackenzie sounds as good. Do you think the names sound good together? I don't want to ask people we know since we want to keep it a suprise.. help!
