Bad weather can be beautiful, but also seriously uncomfortable and even dangerous. If budget is no real concern, this is what I would get for a longer solo bike tour:
Tent: Hilleberg Nallo 2. If you want a slightly sturdier but somewhat heavier version, get their Nammatj 2. The ultimate, simply.
Sleeping bag: PHD Minimus or Minimus 400 depending on required temperature range. For whet weather, choose the Dryshell Fabric.
Mattress: Exped Downmat 7 for below freezing, or the much lighter Thermarest Neoair for temperatures down to about 5 degrees.
A down gilet (mine only weighs 150 grams)
gloves, a buff, some warm socks, a pair of Sealskinz socks, waterproof clothing. Leg warmers to wear with your cycling shorts.
If budget matters, Alpkit do some nice stuff for rather lower prices than the premium gear.
In your case, you already have some gear that you probably do not want to throw away, even if it is more for summer than anything else. A down vest is probably the best way to extend your temperature range. You can wear it in the evening, but also inside your sleeping bag. Do get gloves and a buff or even a fleece hat as well. On long cold descends, wear your rain trousers. When you cross the Alps, you may have to stay in a hotel for one high and cold night.
