There are plenty of companies that make controllers for this kind of setup. Granted, they are typically not powerful enough for SOTA drivetrains, but it's a question of time.
Power electronics will need to fit into the footprint of the e-axle. Or maybe you'll need to manufacture a new housing. Both are easily doable for small companies.

Again, an independent manufacturer can easily make them.

As cheap as the mass produced ones with the economies of scale? I seriously doubt it. You're talking about a car ECU. Go see how much ECUs cost that don't deal with power electronics.

Yeah but again, for how much? You can make anything if money is no option. But if cost is too high people will just scrap the car and buy a new one.
