Color recovery from B&W only works from the PAL systems.

Since all three colors (encoded) are transmitted at the same time, there is no way to do NTSC, except to actually film it in color. This was a Hot Kine, meaning that the head of each one hour camera reel had to be telecast three hours after the tail cleared the camera! That speed wasn't possible with any color processes in use at the time.

(Color negative was very temperamental, plus it could not yield a good sound track, so the track would have to be exposed on a separate roll of B&W negative stock and the two rolls of film synced up and then printed. That took a longer time than they had. Color reversal stocks of the era were too slow, except for Anscochrome , and that stock could not yield a good track. Nobody was magnetically striping 16mm with a coating that was good enough to survive the chemical processing. )

They could do three separate reels of film, RGB, or maybe YUV. YUV might be an easier choice, as slight mismatches in image alignment would be less serious. As U and V are about half the resolution of Y (B&W). The TV station would need 2 extra telecine machines, and feed their outputs to an NTSC encoder set up to use YUV. That's starting to sound too expensive for the day, though...

It would be less unreasonable if three stations interconnected by network lines each brought one telecine to a common location for what you describe.
For a timezone like the west coast I could see that kind of collaboration being feasible.
