I would have ditched the A1200 and come out with 2 A4000's a low spec version and a high spec version. The low spec version could be 020 and 32 bit zorro. Then have a high spec version with and 030 or greater.
Get rid of the A600, but keep the CD32 as the 'wedge' system with optional keyboard & mouse.
CD-Roms were a great cost saving after the initial investment. Staying with big box systems would make it easier to add RTG, 16 bit sound and a CD-rom. It might have made the difference.
