That would be not good.
Imagine a stack, where you have one red plane in front, and a green plane
in the back. RGB volume rendering would show the red plane, but your
method would show something orange in the middle (because in the
green-only volume rendering, nothing hid the green plane).
So, I think you'd have to enhance the volume rendering plugin to account
for RGB. Maybe it would be easier by using ImageJ3d:
