I would actually really hate that because of the fandom. We'd be hit with a whole bunch of "this is all Narsaks fault" or "haha Narusakus get a secondary ending out of pity". Like I'm pretty sure none of us want to go through that, because we'd just be painted as the bad guys all over again.
Honestly, we'd still get attacked whether it happened or not. Heck, we're being attacked now. NH/SS probably know how bad the ending is, but are so deep in denial, they're attacking all anti-enders, claiming they're butthurt NaruSaku fans. Even if they don't ship at all.
As for the question itself, it would be very bittersweet. I love NaruSaku so I'd be happy to see it...but ultimately, I'd still hate Studio Pierrot and the ending. It would be very hard to accept at all since we'd all know it would be a disgusting attempt to bring us back. Nothing they can do can fix the abomination they created. Them and Kishimoto.
I honestly think they only way they could make it right is to redo the ending and/or manga and end it right. (The current ending and The Last and Gaiden being non-canon) Also I want Kishimoto to apologize and confess everything.
