That is a very, very, very interesting, albeit hypothetical, question re: the Ocean Couse scenario. A very sticky one too for us "classicalists". In fact, it's a question I've been struggling with, very much, while trying to complete my forthcoming book, tentatively titled "Preserving the World's Great Golf Courses".
Pete Dye is pretty clear with his opinion that golf courses need to be updated to keep apace with an ever-changing game. He's already made significant changes to a number of his own original designs, including Crooked Stick, Harbortown, and the Ocean Course for this very reason.
I'm certainly not trying to speak for Mr. Dye, but I think if further developments in playing equipment technologies and player development warranted an upgrading at the Ocean Course in order to host an event the Kiawah Island Resort was keen to host, he would be for it. Even if he wasn't around and Doak or Nicklaus undertook such a renovation.
There's no doubt, too, the fact that Donald Ross was ready to redo his 1916-17 design at Oakland Hills some 40 years later says something about the game changing and the need to keep courses apace.
Back to the Ocean course... if the PGA Tour pros of 2015 are driving the ball 500 yards, I'd hope that Doak or Nicklaus or whoever was called in to renovate the Ocean Course would be sensitive to Dye's original design, style, and vision, while at the same time making changes necessary to challenge the world's best players.
In essence, the most successful restorative-based work completed at classic courses to-date has followed that basic philosophy.
