Joel,
Sadly I would say Sharpe Park is already gone. I don't think there is really anything left there that is MacKenzie, even though its still a golf course.
Lincoln Park though can still be saved and with a bit of TLC can be turned into a fantastic gem. As has been said before, it'd be the perfect place to hold a PGA match play event, even if it was in the silly season. With the draw of San Fran and a decent size last place check I'm sure they could draw a very nice 16 man event in November when the weather is the best in them parts.
