So a rinnegan is out, but what about about a sharingan that can turn into a rinnegan like Madara's and a Rinne Sharingan?

Despite the paradoxical nature of the the second situation I see it as one of the Narutoverse loopholes, therefore possible. Since the jutsu allows the user to re-spawn after the user "dies", in doing so fulfilling the consequence of using certain death techniques. Just a thought.
