So, I've successfully re-installed the STB on my '02. Dan Blomgren provided a lot of inspiration. I ground out relief in the left-hand side of the STB for both the bypass-actuator and the outlet manifold, and raised the STB on the brackets using a short stack of washers (entirely as described by Dan).
While the JRSC does tease the hood, it's at the front of the outlet manifold where the hood curves down; there's plenty of clearance between the STB, even raised about 1cm, and the hood. Clearances were checked using plastic modeling clay and I made an effort to rock the motor a fair bit.
I'm sure I've weakened the STB but I doubt it sees enough stress for that to make a difference. For what it's worth, the car feels subjectively tighter- handling again, though this could be my imagination.
Thanks to all that offered advice and helped out, especially Dan.
