Tas layering system based on existing gear

If you already owned the items listed below (I do) what would use use / replace / acquire to make upper body layering system(s) for active and camp use on multi-day walks in Tasmania?
- Columbia Outdry Ex Featherweight jacket
- Mont Power Dry Silk Weight long sleeve crew
- Macpac Nitro Polartec Alpha pullover
- Patagonia Houdini
- Random fleece with neck zip and low collar (280g)
- Uniqlo 'Ultra Light Down Jacket'
I'm thinking tracks across the range of OLT, Three Capes (free), Freycinet Circuit. Other names ringing in my head for the future include South Coast track, stuff in WoJ and Frenchman's Cap. Will usually choose to walk outside full winter but either end of the season isn't out of the question.
Thanks!
