I adore nn
Evie, and I like
Evelyn for it's sake. :)
Evelyn is very classy and I don't think it will become too popular anytime soon, at least in the U.S. Of course, that does depend on your definition of "too popular," as it is rising steadily.
Alice is ok, but not a personal favorite. I love
Caroline, but I don't really care for
Carolyn at all. It sounds a bit too dated.
Your existing combos are quite nice. I like
Alice Elaine,
Carolyn Rose, and love
Evelyn Maeve. Beautiful, though I like the honoring on the other names. A few other pretty and classic, but not too frilly middle names that you might like:
