It would be interesting to see them attempt to turn the group face. Really it shouldn't work. They're basically a cult, it's hard to endorse that kind of thing on television.
Then again, subtle changes to their characters could turn them into effective heroes over time. Mankind went from tortured soul to lovable hero in a short enough period of time.
Wyatt could be a more effective modern day take on the Undertaker's face character. Using mind games to exploit the weaknesses of his heel opponents. He'd see through their bullshit and tear down their facade of strength. They could start to consider themselves a group of avenging angels, trying to rid the company of its hypocrisies. It could make for a fun run if done the right way. Though they're probably a better fit as heels in the long run.

Ninety-nine point nine percent of wrestling fans know wrestling is fake. So now they don't boo bad guys, they cheer them for great performances. Usually they just boo people they hate (heel or not).
You're right about today's fans, but I still think that good storytelling usually leads to fans cheering for the faces and booing the heels. In the best movies out there, you rarely want the villains to win no matter how compelling the actors or characters are. People naturally want to root for the hero.
The problem is that WWE's heroes are incredibly boring for the most part. The bad guys have personality; the good guys all seem to be cut from the same dull mold. It's hard to care about someone who you can't empathize with or relate to in any way.
It doesn't help that WWE is obsessed with making their heroes seem strong. People are drawn to the underdog story. It gives them something to hope for. That's why Daniel Bryan is popular at the moment - because he was portrayed as lesser to his opponents but he kept proving them wrong. In movies and television, most of our heroes start as underdogs. The opening shot of Star Wars wouldn't be nearly as iconic if it was a shot of a huge ship chasing down a slightly LARGER ship. But in wrestling most good guys (take John Cena as the obvious example) are clearly better than all of their villainous opponents and basically can't lose.
Supporting the good guys just isn't fun in WWE most of the time. The bad guys are more interesting AND they're the underdogs. But that's why people loved the Daniel Bryan story so much at the end. He was compelling, he was the underdog and Triple H was playing the heel role perfectly. They took everything that they usually get so wrong and turned it on its head.
