perhaps, but the problem is making it play nice with composite. 
Because it's an overlay, composite can't blend it with the graphics
layer.  I suppose you could some how exclude it from composite and
have it handle it's own blending, but I don't know how hard that would
be.  Take a look at the xorg or xserver archives.  there was a
discussion about dealing with overlays and composite a while back.  In
the long run it's probably better to implement Xv as rectangular YUV
or RGB textures so they can be composited.
