What I'm trying to achieve is essentially the same concept as the way transistors are mounted on the external heatsinks in most amp cases. However, I want to use a smaller heatsink, mounted internally. This would be instead of the heatsink and transistor being mounted referenced to the PCB. The intent being to be able to use a larger heatsink and have the heatsink and transistor securely mounted to the case.
Trouble is, I can't find generic heatsinks with this sort of "lip" for mounting. I'm sure I could modify a traditional full-finned heatsink, but I'd worry about not getting a smooth mounting surface.
Does this sort of design have a name?

Too far away for you but size and thermal resistance might help hunting for similar ones.

Yeah, that’s exactly the sort of thing I’m looking for. Ideally I’d like more fin area. I have enough room for like, 75x150mm, probably more. Thanks for the links!

The heatsinks for these transistors are already mounted internally. I'm looking for a way to increase the size of the heatsink, and also mount the transistor directly to the heatsink/case, as opposed to currently where the heatsink is mounted to the transistor and just supported by the transistor legs.
