Whose 4 faces would you carve into the 'Mount Rushmore' of country music?

There would be so many choices that any could and would be correct . I think I would choose;

Roy Acuff - bringing the the music from the rural areas to the city

Hank Williams - the first "superstar" with the appeal to reach a mixture of young and older audience

Buck Owens - for bringing the West coast/Bakersfield sound to country

Johnny Cash - for opening country music to the modern sounds

Hank Williams, Willie Nelson, Johnny Cash, George Strait

So many others fit here You need to have Strait representing modern country

Maybelle Carter

Chet Atkins

Too bad there isn't room for Maybelle Carter or Patsy Cline. (Maybe swap Maybelle for AP Carter)

Edit: upon reflection. Maybelle up, AP no room

(It feels weird not to include Loretta Lynn, but... she isn't as big a giant as the others.)

Oh my goodness, who do we take down to put up Johnny Cash?
