The only red-haired female elf to cast is Nerdanel. So, if you want her red-headed, that would be the only option I can suggest.
For blond female elves, we have Galadriel, Idril (not cast as an adult yet, but we'll need her eventually), Indis, Elenwë (Turgon's wife, a very minor role), Amarië (Finrod's girlfriend, also a very minor role)
If you're okay considering silvery-haired elves, there's Earwen (daughter of Olwë - the wife of Finarfin and Galadriel's mother). And (much later) Dior's wife Nimloth.
