nope as Copper require two memory cycles to change CLUT - CPU can do this twice more frequently but even assuming Copper and 2 bitplanes so unthrottled Copper there is no software capable to provide such quality on 2 bitplanes - sad... and Amiga HW allow to use 16 colors not only 4 in 640 pixel mode so time requirements are significantly relaxed when compared to ST.

Well, once again - temporal dither is highly optional - problem is somewhere else, side to this i believe that difference between 7 and 8 to create 7.5 with proper spatial dithering will be marginal (draw in interlace mode single line with grayscale 888 imposed on background 777) and there is a chance that on LCD it will be barely perceivable due nature of modern displays (btw temporal dithering is common practice nowadays in LCD's and PDP's - issue if refresh rate)
