The varios are....variable...why don't you just use the built-in potentiometer? Also, they don't have RPM wires at all, so that point is moot.

The DDC's do have a RPM wire, which you can just bypass the rheostat, and plug into whatever you like. Does that answer your question?

I'm sorry if I've missed your reasoning in a previous post, but why is it so important to have your pumps variable? It's not always as simple as 'less flow when the load is low'. My D5 Vario gave me lower temps on '3' than it did on '5', probably because of heat dump. I wouldn't have wanted it lower or higher. Does that make sense? Maybe your situation is different from mine though.
