If someone agrees and wants to implement something like this easily - autohotkey lets you do this in Windows with a one line script.

CapsLock::Ctrl ; or some other key here

To leave yourself some flexibility on using capslock still by hitting shift+ caps to activate it, use

+CapsLock::CapsLock

CapsLock::Ctrl ; or some other key here

I map it to F13, which I then use as a combo key to give me a variety of media keys that my keyboard lacks natively.

Scroll lock is likewise mapped to F14 because that's another useless key.

That's clever, I beat my head against the wall a few times trying to force direct mappings to other functions.
