Guess you didn't thoroughly read through the most recent thread on WFME or the other threads over the years addressing this situation.
Just because Z100 (formerly WVNJ-FM) did this in 1983 doesn't mean it can be done with the 94.7 frequency at this time.
Different set of signals and spacing in different communities to deal with.
There's a very good reason that 94.7 sold for an (alleged) $40 million and 98.7 and 101.9 just sold for roughly $75 million apiece.

================================================
Once more, with feeling:
WMAS-FM is not the biggest obstacle to moving 94.7 into Manhattan. WWSK 94.3 on Long Island is. Unlike some of the other second-adjacent situations that have lent themselves to move-ins (93.1/93.5/93.9, 96.3/96.7/97.1, 103.5/103.9/104.3), the Newark and Smithtown signals were fully spaced in 1964, and thus are not grandfathered and must continue to obey current spacing rules. And there's not much (if any) wiggle room to move 94.3 out of the picture - it's already short-spaced to WYBC-FM, among others.
There's also a huge obstacle to downgrading WMAS-FM, and that's the COL change to Enfield a few years back. Any downgrade to WMAS-FM must still put a 70 dBu signal over Enfield, and that means (a) a less-than-optimum signal over the core of the Springfield market and (b) moving the transmitter site south from downtown Springfield, which is exactly the direction you don't want to be moving if you're hoping to open up space for WFME.
