Schematics and code will follow.

I replaced the 2 x 16 connectors with the actual tlc5940.
The tlc5940 has 16 outputs, but 3 of those will be fed into the 2 4051s to select which input is desired, 2 more tlc5940 outputs will used to populate the enable pins on the 2 4051s allowing us to inhibit one or both of them
PWM is nice, not essential.
