Well, I was thinkin' more along the lines of Shooting 4:3 (which, from what I understand, is an High Quality -- cause you can't really say HD -- 4:3 pre-cropped out of the 720 or 1080 frame) with the HPX170 and adding a 35mm adapter with Anamorphic Primes (Lomos come to mind. Where's IAN D AT!?!).
I might have this completely backward, you shoot 4:3 cropped out of the 1080 mode and with your adapter + anamorphic setup and then conform it to a 2.35:1 ratio, it should work properly.
The only thing is that you're stretching pixels as well so who knows what the quality will look like? I'd surmise you'd have to apply some post sharpening because of the softness.
This is all theory, though. Not sure if that actually works.
