I like it. I don't think saggy will be an issue, unless you pronounce it sag-uh instead of saga. I actually really like the pairing of
Saga and
Freya! It brings out what I like in
Freya-- lately I've been seeing
Freya with cutesie names like
Maisie, and I don't think it fits at all.
Saga and
Freya would be a great sibset. They're both a little dramatic, but I like that. And I think they're both totally manageable because they aren't long or complicated, and they aren't unheard of.
