I'm curious, Can a ZII bus be doubled if if not using a Toaster. What may be the pitfalls of this. There must be some way to increase bandwidth to give lets say a Vampire better performance. A graphics card could benefit.

Vampire sits in the CPU slot on an A2000, or in the CPU socket if you can cram it underneath the drive sled. It doesn't use a Zorro II slot.
Don't know about overclocking the bus, I think you're hitting limitations on the old Buster chip in the A2K (as well as probably numerous other components); it never had any revisions or updates like the A3K/A4K Buster chip did for improved performance.
See pic of Vampire installed in A2000 that I copied off Google+ a few days ago:
