I wouldn't mind if Vader appears in Rogue One with Hayden kickin' around inside the suit, if he really wants to. But Hayden in the sequel trilogy doesn't compute.
Even if Vader appears in Rogue One, why use Hayden? He may have buffed up for the prequels, but his scene as the masked Darth Vader made it very clear that he's no David Prowse.
I agree that I don't really want him to appear in the sequel trilogy. Partly because I'm not a fan of his performance, even though I believe Lucas' inept direction to be partially responsible, and partly because Anakin's story has been told.
If it's little more than a cameo in Rogue One, getting Prowse back in the Vader suit would be a nice way for the new regime to put all those years of acrimony with George to rest.
Yeah, provided they have any interest in doing that. But yes, giving Prowse the chance to return to the role would be the decent thing to do.
Old Dave isn't young anymore.
Neither is Peter Mayhew. I'm assuming Vader will act much like he first did in ANH, and not run around and bounce off the damn walls like some PT reject. Prowse appears to be mobile enough for that...
