Is it too many syllables?
I don’t think it is. Granted, I rarely ever think anything is too many syllables. It’s a very darling name!
I like the names better separately, I think it could work as a sibset: [name_f]Luisa[/name_f] and [name_f]Ophelia[/name_f]. I think it is the repeating -a suffixes that bothers me.
I think it’s so pretty. Not too many syllables at all. I stylistically prefer either [name_f]Luisa[/name_f] [name_f]Ofelia[/name_f] or [name_f]Louisa[/name_f] [name_f]Ophelia[/name_f], but either way it’s a gorgeous pair of names.
I think it sounds fine
