I haven't simulated this to check but it may be the case that IO pins become a limiting factor. The Cyclone IV has 153 IO pins so the design would have to use less than ~15 to be able to fit 10 copies on.

Well a CPU doesn't inherently use any I/O pins so that shouldn't be a problem.

You can easily add some logic to let CPUs share pins, too.

Good point sir
