The Stratix II development board sounds like a nice idea; however, it is really expensive right now ($2K to $3K) unless you have access to one via work or school. Affordable FPGA evaluation boards today, would be Altera Cyclone II/III or Xilinx Spartan 3e.

I would recommend a similar approach on starting to get on route to an A1200 level of a MiniMig 2.0 by use of a larger FPGA, SDRAM, and an external 68020 CPU (need CBT level shifters) since it is going to take some work to get that really nice soft VHDL 68K core upgraded to 68020 level (Icache, pipline etc ...) and to get AGA graphics.
