I think something trendier with a modern vibe would work best. Some suggestions…

Well, my sister is [name_f]Ansley[/name_f], so my sister & I’s names ‘go’ with hers. [name_u]Shelby[/name_u], [name_u]Mackenzie[/name_u] & [name_u]Saylor[/name_u]. 
You have a world of new-age names to choose from…use another last name-like [name_m]Lincoln[/name_m], or a made-up name like [name_m]Dax[/name_m], or a gender-neutral name like [name_u]Ainsley[/name_u]. Since you’ve covered three new-age categories, maybe go with a noun, like [name_f]Apple[/name_f]…[name_u]Ainsley[/name_u] and [name_f]Apple[/name_f].
The [name_u]Ainsley[/name_u] that I met had a sister named [name_u]Hayden[/name_u].
