The nut driver is for 5mm and looks just like the one beacon_dave provided a picture of. The driver fits into a 11mm socket HOWEVER... none of them will work as the base of the drivers all spin. As Dave alluded to, this "mod" would be a cut and weld.
If I were to do this for real, I would use a 2" extension drilled axially. Chop off the spinning end and insert the driver into the drilled hole. Tap lightly with the wire fed welder and file for aesthetics.
I don't know whether I should be proud or ashamed that I know how I would make that tool - if I was so inclined. "That boy just ain't right."

You could perhaps market that as a 'torque limiter' design feature though...

Alternatively could turn it into an impact socket 'pin drive' type coupling by drilling a hole perpendicular to the shaft to allow you to drop a pin through both it and the existing Tommy Bar hole in the driver. Turn a groove in the shaft over the hole to locate your rubber O-ring to hold the pin in place.
Allows you to quick-change the nut driver after shearing its end off every time you use it.
