On the long thread there's a pic of converted AZ GTi with a wedge with astrophotography setup, quite amazing (davidpark's)
The problem is not being able to use it in alt/az, but rather how much load you can put until the gear gave in. The quality control seems to be varied, some people having problem with the slouch, some people can use it accurately even for non guided AP. I have seen people opening it up to give modification to address it. However I'm not sure if they've rolled another update for it.
I also have seen people mounting SCTs, think 5/6"? You can also plug in a weight on side to balance it out.
Use a long bolt (was it m12/16?) on side, put weight on it. I heard using suppression pads with added weights improves it's load.
