I think you've already answered you question.
I was pointing out the VG30DETT swap as something "possible" given a good deal of fabrication, thought, time, and money. Dave is a crazy car guy, so he is blazing the trail on that one.
So putting a VQ30DET should be a little easier, but you're looking at being one of the first to try that. You have a learning curve to get everything to work...
So is it "as easy" as a RB25DET swap... I'd say no, mainly there are quite a few swaps already done. You can get an idea on "do I need to trim the hood or not, will the turbo clear the steering rack, etc" On the VQ everything is unknown.
What is the "mission statement" (pilot speak for what the hell are you planning on doing with this when done?). For ME it is to swap a RB20DET Automatic, keeping it stock and simple, just a fun "beater" commute vehicle that can creep in traffic and give my left knee a rest (too many years of Datsun Comp clutches!).
