Except there's no indication the armor actual weighs him down at all. In fact, while wearing his armor, Vali has light speed according to Kiba. This isn't DBZ or Naruto physics here, these guys are literally putting on more weight and getting faster as a result. Also, technically his body is already made of scales, the demonic power is just scattered, and he could accomplish that something if he just learned Dragonification, he doesn't need a sub-species to do that.
