If you have to lift it into the back of your car you will definitely notice the loss of 10/12 kg and that seriously impacts the utility of the device and where you can use it- If you could get it down to 25Kg with a quick release column and wheels, you COULD carry it in a shoulder bag and that would be a real game changer for the private user market.

Not irrelevant, just not important.
The height of the CG changes the time constants. A high CG will take longer to tip over, but will require more motion by the base to restore balance for a given angle of tip. In practice, these tend to cancel out.
It does make a difference, though. It also makes a difference how much of the weight is on the glider vs the unit, and how far spread out those masses are on each.
