The only system that was done solely because of the supercharger was the intercooler system. Other than that, almost all changes would have been necessary for an LS7 swap as well (dry sump oil system, lowering the motor, moving the motor and trans back a couple of inches, airbox, etc.) because it is much better to leave the manifold in it's stock orientation and run the intake through the front.
The LS7 is a beast of a motor for sure. It was definitely a consideration when we were doing the original LS3 swap, but for this project, we wanted to go with the "cool" factor with the supercharger and get the biggest (in performance), & baddest motor.
The LS7 would be a bit easier but not by much. Chris is correct that most of the changes would still be needed. The intercooler was a Pain in the a$$ and so was the air intake. The LS7 air intake would be much easier since that manifold could be swapped 180 like we did on the LS3.
