So let's say I do this and I have 450w of Solar going through a 30a Samlex controller.
I presume those are 12V panels. Don't know anything about Samlex controllers, but as long as total Isc of the panels is less than 27A, you should be fine.

I currently have two Interstate 6v in series. Would the 450w be enough to charge four 6v batteries?
It's not just about how many batteries you have. Depends on how much energy you use, especially after sunset. With your energy use - no 110V appliances, furnace being the biggest 12V item - I would say yes. You'll probably go down to 80% by the morning and back to 95-97% by sunset most of the time.
Don't know how you can sleep with furnace cycling. I am running Olympian cat heater in chilly winter evenings and mornings in Central Baja, sometimes leave it on the Low through the night - but rarely, since it's never below 40 and that little heater can be too much. Recently bought a heavy over-stuffed synthetic fill duvet, it keeps body temperature in a comfort zone better than a heater. They call it "down alternative", but it doesn't have the same soft cuddly feel as a real down duvet.
