While he is wearing the Ring of Regeneration your pretender will no longer lose health to disease, so he will live indefinitely. He will also accumulate afflictions *much* more slowly. So this is a reasonably good solution for the medium term. However in the long term he's bound to get Mute or Feeblemind or some other crippling affliction, so you will want to get hold of a healer (cast Faerie Court) or the Chalice. Both these things are very difficult!
