While you're spending the big monies, why not look into 3D printing Si3N4 gap filler plates that go between a heat sink block and the PCB? ;) Doesn't need to be suuper conforming to the shape, but close enough for gap filler pads to be somewhat evenly squished
Ok this is a much watch - ironically because just yesterday I was reviewing some old notes I had when researching rocket cams I was then deciding on purchasing for my model rockets, the one I decided on, 10 years ago, worked great but definitely not 4K.

Do they also emit that sweet smell of burning plastic in their original casings?
