Kinda cool idea! Set you Comfort Control on EC and max Temp and start your car remotely. When the coolant temp reaches warm and there is enough for heat, your car will be warmed up by the time you get in and drive! Keep us posted, I'm curious how this goes!
By the way since your in Spokane, that is where I bought one of my cars with IP damage because the owner was running straight Waste Veggie Oil in winter!!

Don't be doin' none of that!
