Probably so, but this man as I understand it is married. But there are more than a few still-conservative Episcopal dioceses that would be happy to have him as well.
Truth is, I believe the next round of elections will find near 100% participation (as opposed to the lack thereof last time), and that the new Bishop of the ECUSA will have a lot of work on his hands to undo the mess that Griswold will have left behind.
If he wishes, he can convert to Catholicism, become an ordained Priest, and still remain married. I believe there is a special dispensation in the Catholic Church for such situations.
Personally, for the parishioners' (and the Anglican Church's) sake, I'm just hoping the Anglican Church boots out the ECUSA and embraces these six "rogue" parishes.
That wouldn't be a problem. The Roman Catholic church is willing to take in married Episcopal priests.
