If you grind off or drill the rivets out, you can remove the cage. You can then, carefully mark the hole locations in the cage on the center body and drill and tap new holes where the rivets were. M5 screws might be the correct size. And then use M5 screws to fasten the cages to the center body.

It is a lot of work. You should be able to get it pretty clean without removing the cages.

If you do go with redrilling for screws, get pictures and post here.
Darn, would be interesting to know why this method? To me, both from a manufacturing process and service ability screws would have been better. Yes I can get them fairly clean, but I need to have the cage removed to get a proper surface prep on the body and cage to have the best anodize result (which will be black dyed cages, turns out sort of smokey colored and zero dye/clear on the body). Yes I can certainly do the machine work to make this happen, it's not just a matter if I want to run down that path? Thank you for responding.
