I do think i’d put a bit more thought into it. It’d be even more important to me for them to go well together, since they will constantly be said together. For instance, [name]Susannah[/name] and [name]Margaret[/name] are perfectly dear sister names, but as twins they’d be SusannahandMargaret, and I think i’d be more likely that someone would call them S&M!
Beyond considerations like that, it’d be more important to me that they be equal, but distinct. For instance, if one gets a nickname, they both do. And I’d like different beginning and ending sounds. With that in mind, my favorites:
B/B: [name]Judah[/name] and [name]Asher[/name]
B/G: [name]Judah[/name] and [name]Rose[/name]
G/G: [name]Silvie[/name] and [name]Rose[/name] ([name]Sissy[/name] and Roo! Couldn’t you just die?! Only when they were very small, of course)
