Some of the powerlifters I work out with are pretty "ripped" and follow more of a powerbuilding style routine. They still do the main lifts based off of a percentage, but most of their assistance exercises are are done in a high rep range. They also have a light day for the main lifts which is usually 10's and 20's, so again, more hypertrophy based. This isn't a straight BB program, but they manage to look bigger and are elite powerlifters too. Kind of the best of both worlds.
They do a 4 day routine (split), but I'm sure you could do the same sort of thing with 3 days. There program looks something like this:
M- Heavy bench (percentage based), 4-5 assitance exercises done in a higher rep range. We do stuff like Hammer Strength Rows, Pulldowns, DB Incline Press, Shoulder Press, etc. Pick what you need to work on.
T- Lighter volume leg day (10's for squat, 10's for DL, sometimes DE work in there), 2-3 assistance exercises, again pick what you like, could be leg press etc, use higher reps.
Th- Lighter volume upper body day (closegrip bench 10's), 4-5 assistance exercises
Fri/Sat Heavy Lower body day, percentage of max for Squat and DL, 1-2 assistance exercises.
They do a lot more than me, but I sort of model my training after it. I do less assistance stuff and focus on a few other lifts that they don't (OHP).
