In very few markets are there independent stations ready to build a brand new news department and to cancel their contracts for syndicated show. While Miami was not unique, it is one of the few situations where there was a station "big enough" to step in without losing much market influence.
Why would they have to cancel their content contracts? I know subchannels aren't as glamorous as whole integer brands, but a willing independent station could easily onboard ABC as a
.2 channel. I believe this already happens in markets where technical reasons (too few signals for every network) force it to be done. (It's much better, anyway, than in the analog days, when networks like UPN had to settle with being "secondary affiliates" on the same physical channels as competing, larger networks.)
Edit: the ATSC standard also allows a station to make one of its subchannels appear as the
.1 of a different virtual base channel number. I.e. physical channel 8, presenting itself as virtual channels 9.1 through 9.5, could also put another subchannel on-air, labeled as 10.1. A willing independent could thus allow ABC to "appear" to be its own station in this way, for branding purposes.
As for creating new news departments, the viability of every channel in a market having its own, independent in-house newscast is already on shaky ground, isn't it? Here in Los Angeles, 2 and 9, and 11 and 13, are already virtual clones. The worst example I'm aware of is what the Hawaiians have been dealing with for over a decade. There, multiple stations, including big three network affiliates, are sharing the same newscast:

In any case, could an ABC
.2 (or a "ghost" ABC
.1) get by with a newscast produced by another station's news department (preferably one already doing a 10 o'clock for itself, so it could go on-air under different branding at 4/5/6/11)?
