If its not raining, then dont wear a waterproof. Use cheaper, more breathable and comfortable windproofs. You need a winter weight windproof, with good wrist and waist seals, and a high neck. Polycotton, polyester or nylon microfibres are good.
Winter thermal layers dont need stuff like rear pockets, so use std hiking versions.
A sleeveles ,lighweight fleece "gillet" is a useful garment.
Use full gloves, neck-warmer tube, woolen socks with non-mesh shoes, and some wind-resistant leggings. Its easy to overdress, so start feeling too cool.
Donnt forget to take spare layers (eg a waterproof and/or jersey) if you need to stop or conditions deteriorate.
