The AGG architecture is flexible enough to allow any kind of color
format. It's relatively easy to add a YUV pixel format. The tricky
part is implementing the matching blending and rendering algorithms
so. Not me, but some skilled AGG developer should be able to do this.

I think what you want to do *is* to create a new "GUI"..?
