Meh. No thanks.
I watch a lot of women's golf, but meh to this. They have the Solheim Cup, which is good entertainment. And though the Presidents Cup is an exhibition of sorts, adding the LPGA to it wouldn't make sense for the PGA Tour, and it'd make it more of an exhibition and less serious. The men don't know the LPGA Tour players, they don't compete against them week to week, etc. And the course setup, etc. would be totally different (men can play to firmer greens, thicker rough, etc.).
