Dude, "ought" already happened, and it happened so big that we can still use it today! My earliest recollection (gleaned through extensive reading) was the use of "ought" during the 1800s.
Mostly I like it for describing what size shotgun Hubby got for all of us for Christmas one year. We always used "ought" when talking about the guns. ;)
It’s like “thirty ought six”, a .30 caliber round introduced in 1906. Or “nineteen ought six”. Once you get to 1910, it isn’t “ought” any more.
