My thoughts are...sounds like a plan, man.
I'm a little confused though. Do you plan on doing a "traditional" powerlifting program, and follow that with a "power-building" program? If so, I think we're getting a little ahead of ourselves. Let's focus on blasting through the competition, and after that, work on the next cycle.
That said, I'd feel pretty confident with any of Waterbury's routines, and pretty much any of Thib's. Not that any other coaches work wouldn't suit you well. But the two of them seem to prioritize strength and hypertrophy gains simultaneously.
It may also be worth checking out this Mike Mahler interview from way back, when he talked to Jimmy "The Iron Bull" Pellechia, a dude who's all about "Power bodybuilding", and did a 1015 bench press with 3 "spotters":
