All good BurnieM.
A very long time ago, I spent 5 years in the UK. My transport, for much of this time, was a Triumph 650. I had leather boots & gloves, the latest (at the time ) in all weather motorcycle gear - Berber/Burberry/Barba(?) heavy waxed over jacket & trouser. Open face helmet, traditional googles and leather face mask.
Despite all sorts of strategies - newspaper under jacket (s), 2 pairs of trousers, wool & cotton socks, oversized rubber kitchen gloves over leather bike gloves, plastic bags over feet - I FROZE!!.
The UK was/is a cold wet place - There were times I had difficulty opening my hands, after an extended winter ride. No amount of Dubbin seemed to keep by feet & hands dry, even the rubber over gloves/bags only had limited benefit.
There is no doubt that I am a "lizard", much prefer heat to cold, so forgive my rejection of your, well considered, cold weather strategy - no offence intendedπ
