Tha Falcon VDI could[1] be able to work without the blitter as long as you
do not use more than 16 colors.

The problem might be to turn off the blitter: I am not sure if the XBIOS/VDI
functions which cause the problems use a trap or if they instead use direct
subroutine calls in the ROM, which would be 'difficult' to patch. At least
Blitmode is fixed to always enable the Blitter on the Falcon IIRC.

If this is true, VM would really depend von NVDI or similar.

[1] meaning that I have not looked at the actual code in the Falcon 4.04 -
however, the needed routines are there.
