That would be infinitely more useful -- having the speed dedicated to a specific timeline rather than the entire project.

Even a sports event playing at 60 fps is served well by simply using 2x slow motion as we review the play. But yes 240 fps for a few brief seconds of playing time could be entertaining and informative in that scenario.
It could be, but again the problem of audio still arises, I think you're much better off recording on a stable external device that delivers normal-speed audio that can then be manipulated in post. We've been doing this for many decades from film with various audio formats (even mag tape and 35mm mag film) for a long time, and it actually works very well. Sync sound in a camera is not going to be an issue with high-speed insect footage -- just get a very simple audio recorder and a decent mic, put the mic in the right place, and hit record.
