That style of pack is way too specialized for bug out purposes. The idea of neatly organizing your gear may seem like a good idea now, but it is not practical. First off, all those little loops and pockets is extra weight. I also don't see how any substantial shelter, bivy, spare clothing, food, etc will fit. And the price! No fucking way. I'd keep rocking the Condor (can't believe I just said that) if I were you.
As for organizing stuff in a pack, it's way over-rated. Throw all your possibles in a small ditty bag/mesh bag/ stuff sack, keep it near the top of your pack and call it quits. Do the same for your FAK.
