There are several hurdles and problems, but some thoughts below:
1) QL screen memory use is a little strange in the layout - so that tends to rule out all but a large CPLD or FPGA to do the video so that compatibility is maintained
If you go FPGA anyway, HDMI signals can be generated. The obstacle here is to solder modern BGA chips as a hobbyist, and all the ground work to move from a classic chip to a modern one with more pins and more highspeed considerations. But in general I see this closer to realism than other ideas mentioned on the forum.
Since every modern FPGA suitable for HDMI has enough space to include a CPU, my question is: Would you still want the CPU outside the graphics chip, and why?
