Well, it's not a great sketch, but hopefully it helps you picture it. The blue part is the PVC tube which sits in the 2 'V' parts on the base (they could easily be circular instead of V shaped). You would put some teflon pads in the 'V' so that it works like the side friction bearing on a Dob. Then, you attach the platform somehow to the top of the tube - maybe you could bolt the tube between 2 triangle sections. The Dob then sits on the platform. It's a bit like sitting a Dob on top of another Dob mount that is on an angle. Anyway, the point is the tube can rotate in the base. Naturally, you'd need to aim the tube at the SCP.
You could add a couple of stoppers so that it only rotates 5 degrees either side of vertical (so that the scope doesn't fall off). 10 degrees movement would be enough to follow an object for 40 minutes i think. Just reset it when you want to follow something else.
I have no idea whether it's feasible though. Eg, I don't know how you'd adjust the friction so that you could move it by hand without it trying to tip the scope off.
Yes, i like the hiss drive idea too. I love the simplicity.
