Yes, but YUV to RGB conversion can be done with a simple linear
equation. My concern is that if  you want some kind of non-linear
color mapping, it may not be so easy. I'm no expert, so i'm merely
giving the suggestion to let someone familiar with a lowish level
shader language (ARB for example) verify that want you want is
feasable in terms of performance.
