I'm not a fan of matchy twin names. I think I would name them the same as any other siblings. Cohesive names that if they do have a theme, it is very subtle. I don't think of what I'd name twins because I'd just name them my favorite names.
Of yours I like:
Lucy and
Molly,
Phoebe and
Daphne,
Winifred and
Beatrice,
Henry and
Daphne,
Edward and
Diana,
Wesley and
Lilah,
Henry and
Simon,
William and
Henry and
Leo and
Wesley.
