I ride my Wee year round. Down to 15F one morning, that's as cold as it gets here, and we don't get much snow or ice, mainly a dry cold. I have a tourmaster synergy jacket, and first gear heated gloves, I also have factory heated grips which are useless below about 45F, they keep your palms warm but fingers freeze and the left side is not as warm as the right, so I do not recommend the OEM grips. I love the gloves though, I plug them into the sleeve ends of the jacket and they both run on the built in controller on the jacket. I have only used it on high once or twice when it got below 20F. No problem keeping my hands warm. I also have added the handguards that your Vee comes with. For lower body I just wear my Tourmaster Venture pants with quilted liner, wool socks, and boots, no problems there either, but even if I did have problems there, not much I could do as I am about tapped out on electrical capacity on the Wee. Your problem is going to be snow and ice.
