Yeah, I can see all that. There is a serious limit on what a Pico can do with a display though. Even if you send it VT100 commands, what is it going to do with them? At the moment anyway you are still limited to 320x240 and 16 colours (Mode 1 is a special case) by the frame buffer. Getting rid of some of the RAM currently needed won't necessarily gain enough to enlarge the frame buffer by much (a lot of the current program stuff runs from flash). Whether you can get the CPU2/DMA/PIO system to handle something bigger is yet another question.
By all means link two PicoMites together, but there is very little gain for a lot of complexity if the idea is to increase video capabilities IMHO. It would be easy enough to set up an experiment, I think. After all, the display side is a PicoMite VGA with something similar to a VT100 handler running. The other is a bog standard PicoMite.
