Yes it is very likely to work with elves. The norse have the Alfar(I think I spelled that right). Just need to know what type of elf you wish to work with.
The Celtic and welsh have different elves and such. Just need ot know where you want to loook into and why.
If you could narrow it down a bit, as Faerie said, that would be helpful.
And if you're looking to learn more about the Alfar, or working with the Alfar, I can definitely help you or at least give you some solid information and point you in the right direction.
