Since you said "between switching places and the tournament", I have to say no; what you said clearly doesn't fit the bill at all. When Hwa Ryun suggested that Koon&Co participate in the Workshop Battle to rescue Baam, she was still with them.

As for the "long before tournament", since only the 3rd round of the Workshop Battle is referred to as tournament--and there was a fair break between the rounds--this could mean that the swap took place after the 2nd round, after the 1st round, or even before the 1st round as you suggest. That said, there is (as far as I recall) no way to tell when it actually did happen from what she or other characters said.
