So, instead of a simple spell that revives a follower. How about they waiting at Shor's place in Sovengard and you can bring them back?

I'm assuming that you have posted in the wrong forums and meant to reply to something in the Modding forum?

Anyway, I think the idea of doing a quest to go to Sovngard to revive dead (as in dead, not recovering) Followers is a great idea.
