Winter glove redesign... ideas wanted

They are big, long, bulky gloves...no getting around that. They're not thin, tight fitting gloves that you barely notice.
They make it more awkward operating or even holding drop bar shifters/levers....but that for me is a trade off i'm willing to live with...better that than to not be able to ride at all...and after a while you just get on with it.

If you commute in extreme cold, or simply suffer from cold hands as you've descrided. I'd strongly recommend the bicycle cockpit equivalent to this.
