I think a rotary broach would work easier. Drill and broach.

Years ago you could buy a bit that would drill a square hole. It was shaped like the rotor from a Wankel engine, mounted off center on a shaft. As it spun, it would cut a seemingly square hole. I don't know if it was perfectly square, but it looked pretty good.
