TSL122 and Marshall 2x12 Cab?

My TSL122 is a 16 ohm 2x12 combo. My cab is a Marshall MC212 2x12 that runs at 8 ohms in stereo, or 4 ohms in mono. Can I run both the combo and this cab together? Here's the back of the combo. It's running at 16 ohms as shown though the dedicated 16 ohm output jack.
If I plug the combo speakers into one of the other outputs and the 2x12 cab through the other, do I set the switch to 4 ohm or 8 ohm? Can it work without problems or issues? Thank you!

According to the manual Wink

using the 16 ohm spkr out negates the other 2 outputs.

The 2 other speaker out jacks are in parallel - so if your 2 internal spkrs are
8 ohm in series (for the 16 ohm total load) you would need a 16 ohm
external spkr cabinet and set the impedance selector to 8 ohms.

so... no - don't do it with what you have. The only option I see you having is
to rewire the mc212 to run mono at 16 ohm.

At least thats my take on it...
