They do any work to the course in the summers, when the bermudagrass grows. So, this won't happen for another 7-8 months. Also, pros can probably use a tee similar to what you've drawn without killing someone on #12 green, but for members taking the tee so far back would be dangerous.
I personally hope that they change the ball instead of changing the 13th hole at Augusta National. Bryson is the only guy taking that new line, and he wasn't a factor on Sunday this year even with that advantage.
