UA5, two wally-world batts, a JB3, optical cable, t-bar, and mics all fit in a Nova 1. Small shock mounts, and small mics (Avantone SSM/KM184 etc) can stay on the t-bar. Stick the strap through your wound-up cables and you have a nice compact rig. It's a tight fit but if you have the optical and battery cables plugged in before you put the UA5 in the bag then you don't have to pull the UA5 out of the bag at the venue. It's so tight a fit you don't have to worry about items moving and scratching each other. UA5 and batts go in main compartment with the JB3 on top of them. Shocks/mics/bar go in front pocket. Small windscreens fit on mics and keep them from rubbing on things. Small Windtech style clamp can fit in flap pocket. Earplugs, Sharpie, flashlight, etc can fit in side mesh pockets. Add a stand and you have a complete open rig.
If you run larger mics or larger shock mounts then you'll have to find other arrangements for them - like moving to a Nova 3 or 4.
