In order for a person to be able to summon Charon and open the portal to the UW, they have to be someone that has been the Hell and back. (confirmed in 5x10).

By that bit of foreshadowing reference, it almost has to be Rumple. The real question is... Why? What is the story here? Isn't the fact they used Rumple because he was killed in 3x11 and was resurrected in 3x15 flashback. Therefore, he had been to Hell and back against his will, well the back bit at least :)
