It would be great if he comes back but I don't see it.
He pissed everybody off when he left mid-tour and now after he dumped Ori (or has been dumped, who knows) he comes back like nothing happened? Naah, that's not gonna happen.

And besides that I don't think that Richie wants to get back in. The HoF induction would have been his chance to spread some words to apply back for his old job. But if I remember correctly he denied all questions related to that topic.
