What would you choose?
My son’s name is [name]Benton[/name] [name]Grover[/name] so those were the first names that came to mind. I see that you have [name]Gabriel[/name] [name]Asher[/name] in you signature so I’ll say [name]Gabriel[/name] [name]Asher[/name] and [name]Bastien[/name] [name]Spencer[/name], borrowing from your sig. 
[name]Bennett[/name] and [name]Griffin[/name].
[name]Benedict[/name] and [name]Gabriel[/name].
[name]Basil[/name] and [name]Graham[/name].
[name]Bram[/name] and [name]Gage[/name].
[name]Grant[/name] and [name]Blaine[/name]
[name]Gregory[/name] and [name]Benedict[/name]
[name]Gunnar[/name] and [name]Bjorn[/name]
[name]Graham[/name] and [name]Bennett[/name]
[name]Gage[/name] and [name]Brennan[/name]
[name]Gwilym[/name] and [name]Bevan[/name]
[name]Barnaby[/name] & [name]George[/name]
[name]Bennett[/name] & [name]Gabriel[/name]
[name]Beckett[/name] & [name]Griffin[/name]
[name]Bennett[/name] & [name]Gabriel[/name]
[name]Blake[/name] & [name]Gage[/name]
[name]Bryce[/name] & [name]Garrett[/name]
[name]Benjamin[/name] and [name]Gabriel[/name] go together wonderfully, [name]IMO[/name]. Other “G” names I like are [name]Gregory[/name] and [name]Geoffrey[/name]. [name]Balthazar[/name] is kind of a guilty pleasure for me, but I love it.
There are so few G names that I like!
I’d probably go with [name]Gideon[/name] and [name]Bennett[/name]
[name]Bartholomew[/name] and [name]Gregory[/name]

[name]Byron[/name] and [name]Guthrie[/name]
[name]Bennett[/name] and [name]Griffin[/name]
[name]Blake[/name] and [name]Gordon[/name] (a poet pairing!)

I like the idea of continuing the 3-syllables of [name]Felicity[/name] and [name]Elijah[/name]. Other ideas could be [name]Benaiah[/name] or [name]Gregory[/name]. Ones that don’t work with that but I like are [name]Bram[/name], [name]Griffin[/name], [name]Gershon[/name], [name]Barak[/name], [name]Basil[/name], and [name]Gareth[/name].

A poet pairing!! As a girl with younger twin sisters… I can really appreciate twin names that are linked in subtle ways. Aka not Frick and Frack, [name]Tristan[/name] & [name]Trenton[/name], etc.
