I think bringing back any former hosts at this point is a bad idea. The View needs fresh blood, not more throwbacks. It's been a while since they've truly shaken the show up; Meghan is the last notable co-host to join. Abby was a wet blanket and Sara was a return, who to be honest doesn't add much of a unique perspective. I think the best thing they can do is boot Whoopi and Sara and bring in a competent moderator + a young progressive. My guess is that Joy will be out in the next few years as well, so I think the show has an interesting transition phase coming.
