You'd have to have a good way to get him there. I had to resurrect a god to go back.
The form of time travel I use simply puts you in your former self. You only get your memories of the future back by going through the same events (you just "know" what will happen if you make a certain decision) or, like me, by getting them again through experiencing the events through premonitions. As he doesn't have a body back there, that form would be worthless. And their aren't too many deities with power over time.
