Dan, if that's what it takes to get the fiber infrastructure you need, more power to you. I would advise limiting your shared infrastructure to the long runs and patch panels at each end. I would also advise installing plenty of spares when you install the long runs, maybe 50%. The labor cost is virtually the same for 12 pairs or 24.
