RB would be the easiest place to try this, no question.

But when you open a BB song in RB, you don't get choruses, the entire song is laid out along the timeline. Which is the point of RB, actually. So do the arithmetic to find out the actual bar number for your target bar in chorus 2 of the BB arrangement and then scroll in RB to that point in the Tracks View. Highlight just the number of bars you want to redo and choose the regenerate option. It must be on the proper BB engine track in RB to do this, but it should open that way anyway since it is a BB songfile. You can also do it again and again in that spot if you wish.
