On the topic of Elves, I would roll a Fey'ri. They kinda neat.
Unfortunately, as interesting as they were, I don't think 5e has them as a race or subrace option (I might be wrong) so it is unlikely they will be implemented as a playable race. Though that doesn't make it impossible for us to have one as a companion as we have a vampire spawn as a companion and typically 5e doesn't have that as a starting option.
