I would probably arrange it like this, if it were mine. That's sort of how I have my rack anyway.
Sequencing and mixing at the bottom, modulation and FX just above that, then filters and voices on top. I got rid of the 2hp ADSR to fit all of your filters in. You'll just have to experiment with placement to figure out what works best for you.
Have fun and good luck.
