Here's the thing: few people really understand what makes a car handle poorly. So you are just proposing another solution to question that wasn't asked.
Offering a 3-link system to a guy who is unhappy with the dump truck-like handling of his 80s barge is going to be hit or miss at best. In my case I have had the opportunity to actively race a G-body, a 3rd Gen Camaro and 4th Gen Camaro; so I know the benefits the 3-link provides over the horrible factory 4-link in the G-body. However, this does nothing to improve the nearly unsolvable understeering condition the G-body platform suffers from. Fix that without extensive fabrication (ala Art Morrison) and then you'll have a hot product on your hands.
Regardless, if you do build this just keep throwing around words like pro-touring, Corvette, rails, bolt-on, etc and people will probably buy your 3-link system.
