Just my opinion, but I think a less-popular format like Alternative Rock would be a dumb idea, for a couple of reasons. First, there's The Planet, which has been around for a LONG time, and still doesn't have such great numbers in Asheville. At least, not great enough numbers for the station which will end up being the second-biggest commercial stick in the market. I'm not so certain there's a large enough audience in Asheville to support that format. For that matter, there's a national trend showing that the Alternative Rock format is a dying one.
Asheville is probably the only market of it's size around without a CHR-leaning station. If you combine the numbers WFBC, WHZT and WJMZ have in Asheville, you have a book that's not too shabby. Also, look at the nosedive WQNS has taken since they separated the simulcast with WQNQ. Why wouldn't classic rock work on the new signal? In the not-too-distant past, Classic Rock had a 6-share.
Finally, and I'll throw this in just for fun...what if they programmed country to try to steal some of Kiss's audience? I know, that may sound dumb at the outset, but look at the way Kiss is being programmed. Just last week they let two personalities go, and more are probably on the list. It'll be an even more automated station soon, I'm betting. If Saga could offer something compelling and some great personalities, they might just steal some of the audience. Look at it this way...Kiss has a huge audience...they could steal a third of it and have a great book. Just a thought. It would really take some hard work to pull off though.
