deck framing question

My deck uses a flush beam -- joists attach via joist hangars. The problem is that the PC66 connector I'm using for the post-beam connection interferes with one of the joists. So I need to frame around it.

In examples I've seen, this is done by doubling up the joists on either side of the problem joist, running doubled 2x members between those doubled joists perpendicularly, and then attaching that problem joists to those perpendicular members. I'm probably explaining this bad. Here's a sketch:


My question: is doubling always necessary? A few pertinent details:

the joists are 2 x 8 and roughly 9' long
the joist spacing is 12" OC, to accomodate diagonal 5/4 x 6 decking

If you live in an area where there are building inspectors, the deck plans should have been run by them for approval. Any changes to structure should meet building codes. Joist spacing and size are dictated by codes. You are good to go on 12" joist spacing for the length of the area. Doubling up? Better safe than sorry.
