This maybe incorrect because last time I did ore gen not in the overworld was 1.4 but from what I remember worldgenmineable finds stone and replaces it with the ore that is specified. In the end however there is no stone to replace so nothing happens. So you will need to create your own worldgen class to replace endstone with your ore.

You can replace end stone with WorldGenMinable, look at the constructors.
