Could Blazing Saddles (1974) still be made today?

Mel Brooks, with his writing partner Richard Pryor, created the classic comedy Blazing Saddles back in 1974. Stuffed with racial and sexual slurs against minorities as well as the Irish, it was a very politically incorrect movie.

If Blazing Saddles wasn't already made, could it still be financed, made and released today?
