Is it possible to have auto aperture in 24p cinema mode on GH2?

So, relatively simple question:
I'm recording theatrical events with two GH2s - one, a GH2 with the 20mm 1.7, shooting wide, unattended on the other side of a theater, and the other GH2 with the 14-140, operated by me for following the action.

What I want is for the wide shot to have ISO, focus, and shutter locked down, but the aperture set to auto, so I have relatively correct exposure without having anyone monitoring the camera. This has to be in the 24Mbps 24p Cinema Mode for quality.

Any recommendations on setting for the GH2 to do this?

Thanks for any advice in advance.

Well i have used all the settings IE manual /auto etc in 24P mode
 
S would work. But if you set ISO too low, it'd be underexposed. Often you'd need to change ISO.

I'd rather pick SS and F-stop manually. Then adjust ISO manually... since PASM mode cannot lock Auto-Exposure.

Basically Creative Movie mode.
 
Stonebat - what I'm trying to do is set up the camera so that only one variable is set to auto, since I can't attend the camera for over an hour, with light levels going up and down. I don't want the ISO going up, since that would introduce gain. I'll lock that down at 640 ISO. I don't want the shutter changing, because of the 180-degree rule (i'll lock shutter at 50, since I'm shooting at 24fps) so that leaves the aperture to be on auto - I just want the camera to stop down for any bright scenes. I can live with some darker footage, but I cannot afford any blown-out footage.

Interesting, I want to achieve something similar (when using the GH2 in run&gun situations), and while it's fully possible using shutter priority (to keep it at 1/50), the obvious flickering when the camera is autoadjusting the aperture is ruining the footage. Now, if I'm using aperture priority program or inteligent auto, It looks like I'm getting the smooth exposure changes I'm looking for (using the 14-140 mm lens), but that doesn't help me much, when I have no control over the shutter speed (please correct me if I'm wrong).

Might sound silly, but I was thinking, if we'd had the option to select auto ISO when using the camera in creative movie mode, manual, would it be achievable to get smooth exposure changes (within the ISO range)? It seemes like ISO adjustments are threated smooth as far as I can see? Anyway, this is not possible today (but could potentially be a feature request if a "third party" firmware became reality..)
