As long as someone have Obito's DNA he can be used as an edo. It doesn't have to be with his body because a sacrifice is needed.But in a realistic sense, it would be impossible, remember Obito crumbled to dust? No body means no Edo Tensei, Shisui is a perfect example.

lol he can just kumai himself to real world
I doubt anyone can find his dorito remains, i mean it's been more than ten years. The wind probably blew it away...
