I love [name_f]Alba[/name_f] for them - something fun and zippy about it.
[name_m]Cub[/name_m], not so much - the Cub/Scout this is a bit much, [name_m]Cub[/name_m] and [name_m]Cruz[/name_m] are visually similar, and I’m not quite sure I like it as a name with the stylish-but-not-at-all-overused vibe of their other names.
[name_f]Lux[/name_f], [name_f]Nyx[/name_f], and [name_m]Reeve[/name_m] are great! I like [name_m]Win[/name_m], but maybe as [name_f]Wynn[/name_f] or [name_f]Wynne[/name_f]. [name_m]Poe[/name_m], [name_m]Reef[/name_m] and [name_m]Whit[/name_m] are very cool - [name_m]Poe[/name_m] has the cutesy feel of [name_m]Cub[/name_m], but the literary feel of [name_f]Scout[/name_f], and the sound-alike [name_m]Beau[/name_m] makes it feel cool like [name_m]Cruz[/name_m].
Not a big fan of [name_f]Alpha[/name_f] (weird internet/ fandom associations, “alpha male” internet things) but I do like [name_f]Larkin[/name_f], [name_f]Story[/name_f], [name_m]Locke[/name_m], [name_m]Kit[/name_m] and [name_f]Rio[/name_f] - especially those last two!
I’d suggest:
[name_f]Astrid[/name_f]
[name_m]Orson[/name_m] (‘bear cub’ - is that too obvious?)
[name_f]Vita[/name_f]
[name_m]Forest[/name_m]
[name_f]Winry[/name_f]
[name_m]Townes[/name_m]
[name_m]Royce[/name_m]
[name_m]Rocco[/name_m]
[name_f]Nell[/name_f]
[name_m]Truman[/name_m]
