I, too, like the Elinor spelling, but that's mainly due to Jane Austen. I still have Eleanor as a middle name for one of my favorite combos, though. I just like the name in general.
If the popularity charts are any indication, than I do see Eleanor becoming quite popular, though I don't think it will become as overused as Sophia, Olivia, or Lily and all its variants/derivatives.
Summer Rose is sweet, but a little hippie-ish.
