Baby names issue????? Opinions please!

[Two Possums]

We had pretty much decided (after lots of disagreeing!) on:

Amali Noa for a girl
and
Charlie Jett for a boy,

BUT.......

Our gorgeous DD (who is 4 by the way!) has decided that we can't possibly use either of these because she has a friend who's lil sis is called Amali (I have already told this girls mum, who is a friend, that we love Amali as a name, and she has no probs with us using it), and DD'S BF just had a little baby sister called Charli (Or Charli Wali according to dd!), and she told me in no uncertain terms "that you can't choose someone else's name mummy!"

What do you guys think about these names? And how do I convince DD it is okay?
(I was really set on these names, and was starting to think of the bub as Amali or Charlie!)

Plus, my DD is Tahlia and I thought the combinations sounded great:

Tahlia & Amali
or
Tahlia & Charlie
