This has been an interesting discussion, but I'd feel a bit more sanguine if either of you seemed more aware of the timeline in the Wayback Machine.
"Musicradio" WABC finally died in May of 1982, switching over to Talkradio on 5/10/82. SuperRadio had been on the drawing board in 1981 and '82, Sklar's baby, and then got cancelled a month or two after The Day The Music Died. At that point in time, Malrite didn't yet own WVNJ (100.3), and it wouldn't flip to Z-100 for another year. At that point also, WPLJ was successful in its own right with their "New York's Best Rock" AOR format; Larry Berger wouldn't get approval to flip PLJ to CHR until mid-1983, beating Z-100's launch by a handful of weeks.
From the perspective of the SuperRadio project, both stations' format flips were a year in the future, and unknown unknowns (to use Don Rumsfeld's immortal phraseology).
Side note: Ingram, Lundy, Barsky, Jay Thomas and the other guys who'd been signed as 5-day-a-week talent for SuperRadio, were to be compensated accordingly. Lujack, Dr. Don, the others who were only signed to do one weekend day each week, also were to be compensated accordingly. Everyone who had been signed had to have their contracts paid off or bought out when the project collapsed. There also had to have been studio arrangements for anyone who was not going to be located in NYC. (This was over a decade pre-Internet, and datacom to do Top40 remotely would have been really expensive for anyone trying to do it from a home studio.)
One other point: at the same time this was playing out, ABC also had just launched Talkradio (or was it TalkRadio?), so the radio division had their hands full, and, I suspect, saw Talkradio as the more promising service to devote their resources and limited bandwidth to.
