Of course it would work. But it depends on the station that airs it, how well it promotes it, if it can make the whole station sound "come together" and not seem automated or robotic, if the signal is strong enough for listeners to wake up to it and also hear in the car on whatever side of town (or downtown) they're in -- and for the affiliate to have a commitment to running the format and making it come across as bigger than just a syndicated music stream they're running, by including big events, and concert promotions, public appearances, etc.
Many music formats, in my opinion, will work in many markets where they aren't being aired. It's usually not because there's no potential audience for it - it's either someone did a lame version of a similar format for a few months before it could catch on, and someone decreed that it wasn't right for a particular market. Or the execution of said format didn't resonate with enough listeners before the station gave up, but still failed to promote it adequately to get people to change their listening patterns (which doesn't happen overnight with most program formats).
I've often found a station I like, and within a few months, it changed format to Mexicano or sports or something I didn't particularly like. Sometimes it was when there was a rapid turnover of licenses, thanks to eager media brokers who were having a field day "flipping" stations. But for any format to have legs, it has to have more than a year on the air, as well as the other stuff I suggested in my first paragraph. But how many commercial radio operators are willing to try something new, rather than copy someone else's attempt at a format? And stick with it while fine tuning it enough to not drive new listeners away? Even if it's a snazzy package like "Timeless Cool" that they only have to plug into, leavingi time for the staff to add local content and work with events to augment the tone of the syndicated program stream.
