Catesetums are growing beyond pot, Some roots are turning brown. Can I repot?

[flowergardengirl]

I purchased two catasetums last week. They are/were in bloom so I did not want to repot them. I am trying my best to not handle them too much (since they are in my quarantine area). However, the roots that have managed to grow beyond the pot are turning brown. I was thinking of slipping them quickly out of their pot and into something a little larger with some moss. Will I hurt them if I do so? We are in the full blast of Florida heat.
