J Allard (THIS IS A RUMOR but it comes from Mary Jo Foley)

Okay yesterday on Windows Weekly, Mary Jo Foley repeated a rumor from an informer on J Allard and Microsoft. Now according to the source (who has a spotty record but is good on reorg information) Allard could be coming back to Microsoft in some capacity. Now let me preface this is a rumor; Allard left in 2010 and has apparently been working on a stealth startup. But he did turn up in the Xbox One video and from accounts he left on good terms with the company. Now from the way MJF talked about this bit of news Microsoft might be courting him to come back. So the question is should he? could he? and would it be good for Microsoft?
