Hello! Always playing around with new combos! Here’s some I came up with. Let me know what you think 
Aaliyah [name_u]Sloane[/name_u]
[name_u]Ruby[/name_u] [name_f]Aviana[/name_f]
[name_f]Fiona[/name_f] [name_u]Briar[/name_u]
[name_u]Kendall[/name_u] [name_f]Amalia[/name_f]
[name_f]Maisie[/name_f] [name_u]Lyric[/name_u]
[name_f]Rhea[/name_f] (ray-a) [name_f]Amelie[/name_f]
[name_u]Navy[/name_u] [name_f]Josephine[/name_f]
[name_f]Della[/name_f] [name_f]Autumn[/name_f]
Hi there.
Here are my thoughts-
Aaliyah [name_u]Sloane[/name_u]-I don’t think that [name_f]Aaliyah[/name_f] has an unpleasant sound. And I don’t think that the singer is necessarily a bad association. But it’s such a strong association, that the name seems awkward to me. The [name_u]Sloane[/name_u] part is very cool though.
Ruby [name_f]Aviana[/name_f]-[name_u]Ruby[/name_u] is fun. It’s vintage & charming & glamorous. Simple & not super duper over done. [name_f]Aviana[/name_f] seems a little bit of a smoosh name to me, but [name_u]Ruby[/name_u] [name_f]Aviva[/name_f] would be amazing.
Fiona [name_u]Briar[/name_u]-I love [name_f]Fiona[/name_f]! It’s my sweet wonderful doggy’s name that you see in my profile pic. 
[name_f]Fiona[/name_f] [name_u]Briar[/name_u] is lovely. [name_u]Briar[/name_u] is botanical yet not in a frilly way, & flows great w/Fiona.
Kendall [name_f]Amalia[/name_f]-Meh, [name_u]Kendall[/name_u] is not my style. It’s a bit too modern & trendy.
Maisie [name_u]Lyric[/name_u]-That’s pretty cute. [name_u]Lyric[/name_u] isn’t usually my style, but as a mn w/the spunky vintage [name_f]Maisie[/name_f], I like it. [name_f]Maisie[/name_f] is darling, even though I personally prefer it as a nn.
Rhea [name_f]Amelie[/name_f]-I want to say this as [name_f]Ree[/name_f]-uh. But I don’t like [name_f]Ree[/name_f]-uh, because it reminds me of diarrhea. I think that [name_u]Ray[/name_u]-uh is really nice though. [name_u]Strong[/name_u] yet feminine & interesting. [name_f]Do[/name_f] you like [name_f]Raya[/name_f] maybe? [name_f]Raya[/name_f] [name_f]Amelie[/name_f] is stunning.
Navy [name_f]Josephine[/name_f]-I just adore the [name_f]Josephine[/name_f] part, but [name_u]Navy[/name_u] seems odd as a name for a girl or lady.
Della [name_f]Autumn[/name_f]-Neither of these names are quite my style, but this is a good combo. It’s simple, different, feminine & smart.
Hope this helps. 
Lovely names! [name_f]My[/name_f] favorites are [name_f]Aaliyah[/name_f] [name_u]Sloane[/name_u], [name_f]Fiona[/name_f] [name_u]Briar[/name_u], and [name_f]Maisie[/name_f] [name_u]Lyric[/name_u] (especially this one 
)
These are beautiful! [name_f]My[/name_f] favorites are [name_u]Ruby[/name_u] [name_f]Aviana[/name_f], [name_f]Fiona[/name_f] [name_u]Briar[/name_u], and [name_f]Della[/name_f] [name_f]Autumn[/name_f]. (I do like @Michelle’s suggestion of [name_u]Ruby[/name_u] [name_f]Aviva[/name_f].)
Fiona [name_u]Briar[/name_u] and [name_f]Maisie[/name_f] [name_u]Lyric[/name_u] stand out for me, I think they flow best!
Agreed- I think these two would make very cute sisters
Aaliyah [name_u]Sloane[/name_u] is fresh and modern
Ruby [name_f]Aviana[/name_f] is elegant but lively
Fiona [name_u]Briar[/name_u] is rugged and sweet
Kendall [name_f]Amalia[/name_f] is okay, but doesnt sing for me
Maisie [name_u]Lyric[/name_u] is sharp but sweet
Rhea [name_f]Amelie[/name_f] is bold and mystical
Navy [name_f]Josephine[/name_f] is well balanced
Della [name_f]Autumn[/name_f] is absolutely stunning
Della [name_f]Autumn[/name_f]
Amazing! I love [name_f]Della[/name_f] [name_f]Autumn[/name_f], [name_f]Rhea[/name_f] [name_f]Amelie[/name_f] and [name_f]Fiona[/name_f] [name_u]Briar[/name_u]!
I like msot of them.
