No way that Kiss will be blown up to move anything over, so long as CHR remains a viable format. I also don't see Jamin going anywhere to put WBZ on FM.
Then there's the slight issue of the calls. Although the Sports Hub doesn't identify as WBZ on air, Beasley still holds the rights to the calls "WBZ-FM." Yet, you're hypothetically going to have Newsradio WBZ on either 94.5 or 107.9? Mind us, that CBS is really the rights holder of the WBZ call letters with Channel 4. How long was Entercom granted the rights to still use the WBZ calls in the merger? I know at some point in the future, CBS holds the power, not iHeart or Beasley. So what happens with that mess? Does Beasley switch the calls of 98.5, which would be nothing as the calls are only used in the legal ID. Or, do they stay steadfast and tell iHeart to rebrand? Or do you have a situation like in (I believe San Fransisco) where WBZ Newsradio is on WXKS or WJMN?
Regardless, I don't see iHeart blowing any FM up to move or simulcast WBZ-AM, be it Kiss, Jamin, The Bull, or any other property.
