You're trying too hard? What's the camera for?
I've never had a need for heated gloves or insoles, I wear thicker wool hiking socks which do fine and winter gloves which have never let me down. If I start to get cold I just pedal faster and in an easier gear and if its below 10* I stay in now, used to commute as low as -10* but don't ever see that kind of temp now that I'm downstate.
I now only buy lights with built in rechargeable batteries that are replaceable. 1750 lumen for 4 hours is longer then I care to ride in the dark anyways and with another 1100 lumen strapped to the helmet, vision is fine and I'd do the same for the tail light.
Course with the GPS, phone, and 3 lights are charging at once its the dining room accessory plug that's starting to look like a tentacle monster.
