Cab enclosure and keeping warm Accessories

I own a 2019 570 utility edition . About to put Comso T4S tracks on them. Love in Northern Ontario. Get cold here. So going to make bike as warm and comfortable as I can for long rides. SoI'm going to put a Cab enclosure bike to start. For warmth adding handle bar heaters, seat heater , already have 2 heated coats, add a good cargo box / back rest that would have to fit inside Cab. I'm good on handle bar and seat heaters. Advise a good Cab and on more was to heat /stay warm and winterize bike or myself. Like heated jackets? Not sure if I'm in right forum or not.
Thanks
