I would prefer if we didn't have a theme. If I ever had twins, I would name them my favorite names and nothing matchy.
From your combos I like:
James Abraham
Isaac James (would also love James Isaac)
Aurora Noelle
Amelia Penelope
Seraphina Juliet
And I would love Oliver Lucas, I think the flow is better that way than Lucas Oliver. I would love to use Seraphina too, but I'm not sure if we have a MN on our list that really fits. But Iäm fine with Juliet if you really like that one. And I think I forgot to add Elliot / Elliott to the list last time.
What about James Elliot, Elliot Isaac, Elliot Asher?
Combos:
Maximilian Asher
Simon Leopold
James Theodore
James Abraham
Isaac James
Aurora Noelle
Amelia Penelope
Seraphina Juliet
Stella Evangeline
Juliet Amelia
Isadora Noelle
