Ummm...what?
OP, please ignore any discussions of 750 nights.
You are correct that you would need 500 nights by 12/31/2018 or 600 combined nights at any point in the future (barring changes to the announced rules), to go with your 10 years.
Should should also be able to qualify with 25 stays in 2018 under the current program rules.
Unless you have a property that will allow you to check-in and leave for $10/night, 56 nights and the thousands of dollars that it would cost seem like a very bad idea to me.
