Even if you disregard the height and only look at the colors, Vanilla is much better.
I think it might be best to change the coloring algorithm altogether. Now it just mixes random colors in layers of one or two stained clay per one layer of hardened clay, but completely random choice. Might be better to just give it a list of good-looking combinations of layers and let it choose combinations from that list.
There, I've pushed it to Git master, go play
You need to set the composition generator to DistortedHeightMap in order to have the new biomes properly composed.
Also, don't forget that the MultiStepMap biome generator won't generate the 1.7 biomes, either use TwoLevel, or one of the geometric ones - constant or checkerboard, where you can specify the biomes to use.
