not really a new idea. ive been using this site for more than 7 years http://www.eradicator.com/ you could always throw a hunters 1/4 inch peep on this rifle site to get 3 point site system. with this type of site it will allow you see and correct any torque caused by poor grip. this usually happens when your twisted up in a tree stand trying to shoot through a pocket of scraggles and branches. i also think its possible to torque the bow string slightly left or right even with a firm proper hand grip. thats why i think adding a peep to this set up will show all of your faults and allow you to correct before shooting at game. just my opinion.
