I think I can take it from here. The limited testing I was able to do did not show any video quality file size difference.
It would be great to control video exposure and compression too.
That said, the exposure is apparently fixed when high-speed video recording starts, so recovering correctly-scaled linear pixel data (which is what we want in our application) from the compressed video isn't as hard as it sounds.
I had some suggestions from one of the Magic Lantern developers about how the video control registers might be organized, so I and my students also might be looking into having a wider selection of video framerates and resolutions, but that's not our top priority and we don't yet know details of how the high-speed video works.
All the other PowerShots I've used with CHDK didn't support slow motion video, and I never really looked at the CHDK video support....
Will the Powershoot N fit such a setup? i.e. will it possible to control it using chdkptp and will it support 'remoteshoot -cont'?

1) External power supply (Battery Pack) for extended video play but plugging the camera in automatically loads playback mode. I have been trying to read the forums to see if this is something in development? (trick camera into recording while being plugged in)
2) Extended video recording times. I managed to find a few scripts where it automatically continues recording a new video file which is good enough for me for now. (I can't for the life of me find those scripts again!!!)
