I prefer common but not too common names so I have just written the first things that pop into my head then rearranged them in order of preference

Boys

Jett. - Let's fly Jetstar! Probably my fave though
Ethan. Love it. Little bit too common
Cruz. OK - Tom Cruise, Cruz Beckham Hmmmm.
Harrison. Like it but definately not with your last name.
Henry. OK, don't love it though
Milo. - Yummm. Not as a name so much.
Felix. - the cat. & Probably not the best name when you already have an Oscar.
Chasen. Least fave.

girls

Imogen. - Love it - my number one pick from your list
Milla. - I like it I love Milly.
Edyn. - Pretty. I think I prefer the more common spelling Eden.
Ayla. - Pretty but I prefer Isla.
Sienna. - Love it - quite common now though
Indi. - Cute.
Mia. - Pretty but way to common ATM for my liking
Ruby. - Like but not love - quite common
Saige. - Like it but don't love it. It's a herb.
Bryony. - Pretty
Alizae. - Sounds pretty, but will it be hard to spell?
Zayleigh. - Sounds pretty but I don't like the spelling - maybe Zaylee instead
Immaliah. - Sounds pretty but I don't like the spelling - maybe Imalia instead
Charli. - I'm more traditional & think of this one as a boys name. But I wouldn't pick it as a boys name because it is used as a girls name too often.
Chelsea. - Like it but don't love it
Ayah. - Sounds like it's missing something
Asia. - OK but don't love it
Brynn. - Don't like it.
Channing. - Don't like it. Doesn't sound like a name.
