Why don't you and your mates drink 10 pints of lager each and piss down the climb. That should warm it up. Reminds me of this: youtube.com/watch?v=f8-0m0VI7J0&
Drop right down the grades, hanging off axes and or tight leashes on steep ground is tough on the hand circulation, plus you keep moving more with faster easier pitches.
Leashes? I'm a "dyed in the wool" traditional scottish/hiberno snow thrasher and I gave up leashes on mixed in 2015 and ice the following year. I use lanyards (I certainly don't want to be nominated for the Darwin Awards, all because of a dropped axe on a Nevis classic).
I once tried to get out when it was -38C at 3800m and it was so cold that I could barely breath. When I adjusted my headgear and exposed so flesh, it felt like my face was being ripped off.
Interestingly, if you had mentioned ODG a couple of decades back, I would have known what you meant - had a good weekend away with the Newbury Mountain club about then.
