I really don't think rigid tapping with a roughing and a finish tap is practical. Probably the only way to do it would be to rigid tap with the plug tap, change to the finish tap but leave the holder loose and manually start it into the hole, and let the existing threads synch the tap. Then, tighten the tap holder while it is still in the hole. This is not what I'd call a reasonable shop operation.
