I think it's likely. But, ABC will likely commit to something for both WABC and WPVI, and some of its other stations elsewhere also, so they'd likely put something new on the daytime lineup also, and not just local programming (news).
That said, they could move all the soaps one hour earlier, run something new at 3pm, and then a 4pm newscast. However, the Action News at Noon, with Millionaire, is likely #1, so I'm not sure they'd tinker with their noon hour. KYW and WCAU can afford to play around with it, because they aren't #1. Maybe OOL moves to AM (just like Guiding Light) before eventually ABC cancelling it.
I also suspect KYW would likely move Dr.Phil to 4pm and run news at 5.
