I'm not a fan of matching sibling names, especially names that rhyme. I think it would be better to give them their own distinct names.
Combinations I like:

How about giving them all their own middle names? You have a lot of nice names on your list. The ones that you don't use could be used as middle names.
Anne,
Lee, and
Grace would go together well as middle names for the girls.
