That's just color1 and color2, you have color0 and color3 in multi too, and you can raster them.
For dfli you have (121*60)^2 combinations of color0 and color3 for two raster lines and 121*60 combinations of color1+color2 for each character. To do all the combinations for only 4x2 (multi) pixels it is about 3.7*10^11 cases. I guess you don't try them all, especially if you play with xshift too.
So, to speed up the search, you need some heuristics to find local minimums at least because the searching space it too big. The method I mentioned typically finds the local minimum for a normal multi image in 10-15 steps and it optimizes color0 and color3 too.
I will get back to this topic with sample conversion results when I have support for dfli + xshift too. My method can't optimize for xshift, so I have to combine it with some other heuristics.
