You could only do that through very specific DSDT programming. You can scrounge the Net for it but it's a little complexed. There's a good chance brightness control works through Fn-Ins and Fn-F3.


You may also try an app called Karabiner to remap your keys. From memory, it supports Mavericks, Yosemite and El Capitan.
