Names for older adopted sisters

I am adopting two sisters 7 & 10 from overseas. They will keeping their first names (which are lovely), but I would like to gift them middle names. I want to choose names that speak of my hopes for them, that are meaning rich, but also that allow them skope to play with their identity as they mature if they wish. Therefore, I like longer names that have several nn options. Culturally in the girls’ home country sibling names match or rhyme, so I want to keep this custom through alliteration or similar syllables. Their first names are 2 syllables and do rhyme.

I am quite settled on my older daughter’s names but and having trouble deciding on my younger daughter’s names. What combinations go best together, or are there other suggestions.

Older Daughter
[name_f]Valentina[/name_f] [name_f]Kate[/name_f]

Younger Daughter
[name_f]Talitha[/name_f] [name_f]Jane[/name_f]
[name_f]Talitha[/name_f] [name_f]Faith[/name_f]
[name_f]Viviana[/name_f] [name_f]Jane[/name_f]
[name_f]Viviana[/name_f] [name_f]Faith[/name_f]
[name_f]Vivianna[/name_f] [name_f]Faith[/name_f]
[name_f]Vivianna[/name_f] [name_f]Jane[/name_f]

I also like [name_f]Dorothea[/name_f] and Sharaya

I like [name_f]Vivianna[/name_f] [name_f]Jane[/name_f] to go with [name_f]Valentina[/name_f] [name_f]Kate[/name_f].
