When we regrassed from old Tifway 328 push up greens to TifDwarf USGA greens a few years back, the same question was asked. I told them that quite honestly the maintenance costs will increase. This is due to the newer grass being able to be mowed shorter and also requiring more topdressing, fungicide and fertilizer versus the old 328 mowed at .250". In your case, yes, the newer varieties are more pest and drought resistant, but by what percentage? Skipping a $12,000 application each year, and saving $10,000 in electrical for the irrigation pump won't pay off a $250,000 renovation anytime soon, and when it does, the grass will be old technology and you'll be looking to regrass again.
In my opinion, I'd find the other benefits of the renovation, and sell it that way. Sometimes updating the course turf and features is a matter of survival. Compare the courses features to the competition. Id' hate to say it, but golf a lot of time involves "keeping up with the Jones'" in order to survive.
