Does it matter ? The QS serves a need for those who have to have the "ultimate" TT, but it's very compromised. No back seats (even though they are all but useless, they're good for carrying things on), no load cover, rock hard suspension PITA wheels to keep clean, no real performance advantage over the 3.2, although it handles better, and seats you need to be a contortionist to get in and out of. If I had one I'd do exactly what you're doing, chop and change it to turn it into "your" ultimate TT, and to hell with the bragging rights !
