6CCD Cinema Camcorder?

I was wondering if this was technically, or econamically feasible for a 6CCD cinema camcorder to be developed. Why 6CCDs you may ask? The first 3CCDs to handle each individual primary color (RGB) & the remaining 3CCDs to handle each individual complementary color (CMY). I'm not sure if I'm talking sense here, but is this at all even a consideration?

I've been thinking about this lately because I researched into high-end digital light projectors that have a 5 speed color wheel. This color wheel is composed of six sectors (Red, Green, Blue, Cyan, Magenta & Yellow filters) & rotates really fast to produce the colors to be projected on a screen.

Also, I've come across this stereoscopic camera system :

Pretty cool setup for a DVX don't you think?

I wonder how they managed to make those DVXs record RAW 4:4:4 color samples & immediately dump them to external harddisks?
 
RGB is the additive (light) primary system; CMY is the subtractive (transparency) primary system; the primaries in one are the complementaries in the other. A camera operates on the additive system; a projector (or dye print process, as in film or slides) operates on the subtractive one.

If you are shooting film or video (additive) then the secondaries don't do anything for you.

The DVXs are outputting in 4:4:4 color space, with the addition of hardware that taps the signal straight out of the CCDs, before it's downsampled/compressed for NTSC/PAL-type recording. Kind of like an Andromeda, or a RED. Maybe exactly like an Andromeda, or a RED.

Remember that you have to split up the light passing the lens with a prism for each CCD. With 6 CCDs you just loose too much light to make a benefit of the additional CCDs.
 
I see, now I understand fully your explanations. Very clear & concise. Thanks.

Since I also want to find out if it's possible to shoot with my DVX & save all the footage real-time to an external harddisk (without using the Firestore harddisk), just a conventional SATA harddisk. Is this possible? I don't favour the Firestore harddisk because it costs $7500 in my country. I feel that this price is way exhorbitant for a budget videographer like me. Sometimes I'm required to do express edit, which is same-day edit. For example, I shoot the wedding church ceremony from morning till lunch time. Then I have to rush back to my studio, upload all the miniDV tapes to my PC & edit from there. Then render & burn the edited video montage to DVD & rush to the hotel for the dinner shoot. If I can find a solution to save the video footage direct to harddisk as I'm shooting with my DVX that would save a lot of time uploading from miniDV tapes. Thanks for your advice.

A lot of people have tried just plugging a normal hard drive to their camera but with no sucess. It's not possible at this point.
