Appreciate everyone contributing! I will use my hidden city ticket purchased with points and ask the WN rep at the initial boarding gate to delete my second leg. The next day I fly WN out of the hidden city. Regarding the legacy carriers you are frequently advised to book with a different carrier when flying back out of your hidden city destination from the previous flight in. Based on everything that has been shared here, WN's COC does not expressly prohibit hidden city bookings (the only major airline that hasn't) though WN no longer explicated condones them. So my flying out of the hidden city on WN the next day shouldn't be an issue for them.
