The following script re-enables Take 1 of an inactive take. I want to do the other way around, but it doesn't seem possible. This would be an ENORMOUS speed-up, since I'm not interested in the video clips while I render audio, and they pose a huge slow-down of GUI redraws and disk payload.

What can be done?
