With that thinking they'd use the 4.3 rather than the 3.6 in the Camaro because it's derived from the gen v small blocks ala 6.2

Engineering is about finding the optimal solution to dozens of conflicting wants simultaneously. Things are rarely done exclusively because of this or that. But there are priorities. And depending on the segment a vehicle is competing in, those priorities can shift around.
My guess is that they were looking to minimize the powertrain cost for the base models of the full size trucks. Using a cheaper engine, that also saves R&D money goes a long ways to that end.
As for the Camaro, using the 4.3 in Alpha doesn't simplify things, it complicates them. The Camaro isn't the only thing using the Alpha platform. The ATS & CTS both have turbocharged engines related to the LGX. So you'd need to engineer the platform to accept the High Feature V6 family anyways. And thats not even getting into the NVH issues with using a large 90 degree V6 in a luxury car.
