Looking at those calipers it strikes me that calipers are very old school engineering. That's a hefty lump added to the unsprung part of the car, where every few grams saved will improve both ride and performance. There must be a better way.
In fact thinking about it there is... inboard brakes. I wonder why they've not been more widely adopted. Cooling and or packaging perhaps.
Apologies for the thread deviation

The unsprung weight on the 20" cars is just crazy. Not only do they have enormous heavy wheels, but they also have steel uprights which weigh 13Kg each to compound the problem. Add big steel discs and the calipers (these do at least have an alloy piston housing) and you've got the weight of a Polo engine at each corner! Its hardly going to help the vehicle dynamics overcome a quarter ton of engine in front of the front axle.

I think you're right on why inboard discs never caught on. They take up valuable room which could be used for people and things, whereas the space in the wheel is otherwise free.

Your ingenuity and determination to find solutions to the problems amazes me

Drilling out snapped bolts with a tool to create a perfect guide hole for a larger bit, then creating a mini piston in a very tight spot to push out an ABS sensor! Bravo!
And then doing that when most people are snuggling up on the sofa watching the evening tele

+1 to what Dean said, although he did miss out on the other crucial job MJ is doing as well, and that is finding the time to photograph and document what she's doing.
