Well, we'll see if you guys can make it work!
I used similar for an 12x8 matrix here
with 8 common cathode 'rows' sunk by ULN2803 (from arduino pins) and just resistors sourcing the anodes - two 6B595s pulled the anodes low for the "off" LEDs.
6B595 & PNP/row is a little more hightech, but is really needed for the much higher number of LEDs that can be on.
