Anyone seen a 3.8s brakes converted to dual master cylinder?

I was wondering if anyone has seen any 3.8s upgraded to a dual master brake setup? I have upgraded the front brakes to the Wilwood kit and the rears to later model larger in-board brakes but still would like more braking power. I have inquired to a place in the UK about an AP Racing front caliper setup which is still only a 4 piston but larger pads and a true vented rotor. I would like to have a dual master both for increased braking and the worry if the single master ever fails... Any ideas?

I cannot help with your question as I still have the original master on my car, but am very curious about your rear brake conversion to later model brakes. What later year/model brakes did you use, and were any modifications necessary to fit the later calipers? Has the conversion been an improvement in terms of brake performance/serviceability?
