The only way to plausibly revive Rin was using Nagato's jutsu, which would have completely revived her as with the people of Konoha. Edo tensei would have made of her a sort of zombi, so no matter how strong Obito's or Rin's feelings were , she wouldn't belong in this world (not to mention its kind of sick)
In any case, if Obito ever lost his chances with Rin it was for all the years he spent locked into that cave, not for her death. She already had a thing for Kakashi, Obito left and then it was only Kakashi watching over Rin all the time. That would explain why Obito has given up on the world and wants to throw it into a Dream, because no matter what he does, he can't get back those years and Rin's heart.
