BTW, I've already touched upon this. In reality, the only thing that should affect the harmonic characteristics of the two crankshafts would be the mass of the crankshafts themselves, but considering the breadth of variables considered (which I admit, I lack knowledge on), I've included some other engine specifications/estimations. Besides, if we're considering other variables, wouldn't you assume that a boosted VQ37VHR engine would behave more similarly to a VR38DETT? (I'm not saying the VQ will behave more like a VR than a VQ, just that a boosted VQ will behave more like VR than an NA VQ.)

The engine is already internally balanced, so there should be no "balancing" act needed for the pulley.
