Because you should first rewrite the OS to use more Chip.
That's the easy bit. It's not even a rewrite, just change the end address of the loop which detects the amount of chipmem...that is assuming a single block of chipmem..but then you run into other problems cos the A1200's memory map is already defined, and there isn't enough space without rearranging it, which means recompiling some device drivers to use new addresses and potential problems with old software that bangs the hardware expecting things like the CIAs to be at the old addresses.
The hard part is the 'expansion board', which will basically be a new A1200 motherboard, with redesigned custom chips that can access more than 2Mb.
