How about either a country leaning CHR (given WKLB's ratings) or a country-classic hits/rock type "we play everything" Jack format: A lot of the 70s-80s hair band/arena rock ballad stuff is compatible with——e.g.——Kenny Chesney, Little Big Town, Rascal Flats, Sammy Kershaw...especially if they used a strong dose of reverb/compression! :

;D :
Could definitely see something like this working, although I'd go light on modern-day stuff as well as the '80s hair band material. A typical 12-song set list might look something like this...
Eagles - Tequilla Sunrise
Johnny Cash - Folsom Prison Blues
Led Zeppelin - Rock N' Roll
Lady Antebellum -Run to You
Poison - Every Rose Has Its Thorn
Jason Aldean - She's Country
Shania Twain - Still the One
Lynyrd Skynyrd - Gimme Three Steps
Glen Campbell - Gentle On My Mind
Carrie Underwood - <insert whatever song here>
Heart - Barracuda
Def Leppard - Pour Some Sugar On Me (personally hate it, but you'd need songs like for the female demo, while there's Skynyrd, Zeppelin, etc. for the men)
That's probably far from perfect, but it's a general outline of what I'd imagine such a station would sound like. No reason in my mind why this wouldn't work; Boston isn't quite the country music wasteland that it used to be, and every country fan I've ever known around here has strong rock roots, men and women alike.
