Unfortunately it wouldn't be difficult, but impossible. Since D7/D6
would be 16 Pixels, which is not dividable by 3, so you could never
exactly match the color change on both ends.

Besides there's another limitation, you can do a colour change only in
intervals of 9, 12, 15 or more  pixels, since even a sequence of 


would produce something like this:

<9 pixels color A><9 pixels color Y><9 pixels color X>

and then you'd run out of registers...

I think Andrew did toyed around with things like that and Robs
Ballblazer attempt should've been something similar too.
