Sounds like you have a handle on your fix, but I am trying to understand what you asked. Do you want to take a song in 4/4 and make it be 2/4? I ask because I had one like that that I wrote in cut time and for the drums I needed it to be in 4/4. I had to save it to a wav, export it, import it into a new session, use the time stretch function, save it to another wav and then import it back into the original song. Never again will I record anything that way! LOL!
