I think the material on Tusk, given that there's more of it, would have been easier to work with and perhaps a little more interesting/off the wall.

But I understand them choosing Rumours - I'm sure they're planning on incorporating the breakup drama into the episode. In fact, Murphy just said this... "We’ve always wanted to do an episode that is not a tribute to a musical act but to an album, and one of the albums that we all three love is Rumours by Fleetwood Mac. … You watch the show with everybody with each other, then breaking up – it’s like the making of the Rumours album!”

As far as a cameo, if Stevie and Lindsey were willing to make fun of themselves I think it could be potentially hilarious if the two of them made a small appearance... but I think they take themselves a little too seriously for that to work out.

Also, I'm consistently seeing Rumours being spelled as Rumors in articles about the show doing the album. It's getting on my nerves haha.

ETA: Another thought, on the subject of cameos... I know Stevie supposedly wants to be on the show (which I find strange considering she's said she doesn't like being filmed nowadays).. it would be pretty funny if the reason the Glee club decides to do Rumours is because Stevie comes to Mr. Schuester in a dream haha.
