I agree with gmoon but if your still interested you could use duct tape and fleece as a temporary plan

How about just a pair of insulated ear muffs?
I use a Buff while I'm climbing. It's thin enough to fit under my helmet, but keeps the wind off.
Seems like an unnecessary complication. Why not just wear a hat under the helmet? I normally wear a microfleece hat under mine. Or a heavier balaclava in colder conditions... It's a simple system and it works.
