Even assuming that it works you are talking about an ounce, maybe, of weight from that spring. Makes no sense to do it.
The weight of the trigger pull on these guns is due to the trigger return spring, sear springs and the friction/over cut interface between the sear surface and the striker hook. Those are the things and modifying the geometry of how your finger movement interacts with the sear are what will make a difference. That's why GG has the parts in their kit that they do.
