If you want to do one mod on that console, then remove that transformer in the meterbridge out into a break-out box.

I had also modded all the auxes to be post-fader, for I almost never needed pre-fade sends in my workflow.

I no longer have that board but if I came across to one now, I would buy it in a heartbeat, despite its lack of headroom.

By the way, you get the best sound out of it if you push the meters to red
