It’s been done for Sony cameras a while back. One of the tools that lets you get into the camera’s firmware is Sony-PMCA-RE. As far as I know this is not the only one either.
It’s not a powerful as a Magic Lantern, but that’s not the point, which is that camera firmware hacks are still going on.
As long as there is a reason and motivation someone will figure it out.
They won’t.
If people could hack the firmware of these companies they would’ve done it by now, but no one has.
Except the old Magic Lantern one from decades ago.

Well no one has figured it out since they stopped supporting the playmemories store in cameras.
