You are a glutton for punishment, aren't you?
Here's the deal.
1) Wedges make it even harder to mount the scope (now you have to lift a 65 pound assembly, then tilt it, then balance it, then thread a bolt into it).
2) The wedge itself must be massive to hold the scope. To give you an idea...I happen to have an older Celestron wedge for their early 11 inch scopes. The beer can is for scale. The wedge ALONE weighs about 60 pounds. Now, "modern" design will make it a bit lighter, but still, it's a MASSIVE undertaking.
3) I just, today, picked up a used 8 inch Celestron Evolution with the StarSense camera. I would be happy to flip it to a needy Pelican. No wedge, but you can do 20-30 second exposures in Alt/AZ and use one of the new fangled programs like Registax to stack those short exposures into something longer....
