A couple thoughts here: First, what kind of music are you hoping to make with this?
Second, you mentioned the "fun factor," which is my highest priority with my rack/music, and always what I encourage above all else. With the collection of modules you have here, do they all have the fun factor? I love Disting and Pam's, but they are not what I would consider fun modules. If you add uO_C to those two, you are REALLY getting away from on-the-fly tweakability due to the menu-driven set and forget nature of these modules. Is that the direction you want to go?
I have a few things that I would probably change about this for my personal tastes and goals, but I'll wait to recommend anything until you respond.
Have fun and good luck!
