What specifically needs to be finished? Isn't it already pretty dialed in at this point?
What happened with the consultant you already hired? How about the help from Roy, Chris, and Mike at the Klipsch forum? They know more about fully active Jubs than anyone here.
The only thing I might suggest is heavy toe-in/cross-fire orientation. 402s control the pattern so low that they can really take advantage of time/intensity trading, which would give you a huge sweet zone. That's how ChrisA has his 402 based synergy horns oriented.
