Activity does not stop miles from expiration, unfortunately. Only status or a credit card does.
OP, book a 100k award far in the future, earn the 12k you need, cancel the award. You will have until the end of the quarter to reuse all the miles (so make sure you cancel at the beginning of a quarter).
