In short, no. I think the idea was to remove the twisting effect of a single spring as it extends. The modern thinking, feel free to correct me if I've got this wrong, is to fit a top hat on the piston end and a decent delrin spring guide at the other end.
When the spring extends during the firing cycle the rearmost end breaks contact from the cylinder and so is free to "unwind" anyway, doing away with the need for double springs.

I used to have twin springs inside my HW97k silencer.

They where no good there as well.

Would one spring cut in two, with one half turned around give opposite wound coils?
