Alright I'll allow his spirit (him) to be permenantly destroyed while he's out of his own verse. When it comes to bodily destruction he'll enter a plane of Limbo, which looks like a place he's comfortable in, where he can repair/rebuild his body.

That's usually how we do it. If you like the idea of having some form of truly immortal spirit, we don't really ever address the concept, so it's not a problem unless he's coming back to life from that kind of a state. In that case, we'd have to figure out how it works within the physics engine. But if it's the "once he dies, he's an immortal spirit that's permanently gone from the physical world" (like what a lot of people consider the spirit to be in our world), I don't foresee a way that it could conflict with anything established.
