It's an interesting thought.
About Star Trek: Federation,
...causes Vulcan, Bajor, and Betazed to leave in disgust at the corruption of the UFP, leaving it with only twenty systems under its control.
We see six stars (for planets) on the flag of the UFP in the new trailer for DISC Season three.
The Ferengi become the dominant power in the galaxy, and make money by spreading the Bajoran religion and making Bajor into a major place of pilgrimage.
I suspect that something that important would have made it to the trailer.
Also, Star Trek: Federation was to be set in the year 3000. From DISC: "Such Sweet Sorrow, Part 2", we know that the crew of the U.S.S. Discovery traveled to year 2257+930=3187.
Despite all the information to the contrary above, perhaps there are still possible connections. Does anyone know if the writers plan on using some ideas from the undeveloped show? Any thoughts or comments?
