move bitplane6, 1 pixels per frame
move bitplane4, 2 pixels per frame
move bitplane2, 3 pixels per frame

It is not possible to have a different x-scroll value for every bitplane of playfield 2; scroll registers work per playfield. You'd need to either shift two bitplanes with the blitter, have 16 copies of them in memory (shifted by 1,2,3... pixels) or use some other trick.
