Assuming you can't get the other broadcaster to cooperate, you can't broadcast with the same "quality" (as defined by resolution and frequency-of-scene-changes) as you could if you controlled the entire 6MHz channel.
There is only one broadcaster. There is only one MPEG2 transport stream, now containing both programs. They must cooperate, as they are sharing one piece of transmission gear. It's not like a cellular network where two different entities are sharing time slices of a common spectrum. Also, I'm not aware of any broadcaster that uses 1080p.
