OK I am a newbie at this so bear with me.
I bought two Futaba FP-T7UAF radios. One is on ch 25 and the other is on ch 19. I then got two Futaba receivers with ch 50 in them.
The method to my madness was to get a channel 50 module for the two transmitters ad use them in a trainer configuration.

Can the modules just be swapped out and work with the receivers?

#2 scenerario....Could I put either ch25 or 19 in the receivers and then get either a ch 25 or 19 module for one of the transmitters to make a pair and work ok? Is there a problem with moving frequency of the receivers?

After I get this sorted out and clear in my head I will know what to look for here.
