That would require hardware changes in the video circuit of the CBM-II.

Adding a second set of U29 and some glue logic could add an attribute
memory. To be compatible with existing CBM-II software it would
probably be best to have two sets of fonts, the standard PETSCII and a
standard PC8 font. That could also add for example color (or grayscale
for the CBM-II HP if it's not too hard to add analog signal levels to
the monitor).
