the problem with possible reincarnation is that the technology to create a body similar their old body doesn't exist anymore. even after the emperor created the first 20 he was unable to re-create them, which is why the legions were created using primarch gene-seed - he couldn't replicate what he'd done. so if they were reincarnated it would only be their mind, physically the best they could hope for is to find themselves in an astartes body
