Its a fine balancing act Steve, of weight v cost v needs and there's been some fine suggestions in this thread.
From the few Bushcraft socials and gatherings I've been to, most enthusiasts never walk more than half a mile from their car, and that's fine as they like to enjoy the surroundings with a certain amount of comfort and luxuries.
However, from your OP you seem to be talking about travelling greater distances and still enjoying the trip? I was reading this thread and thinking about my 'standard' gear which really doesn't change much from season to season, or from outdoor activity to activity.
I only use a tent, when I'm probably going to a campsite and require 'security'. Otherwise a tarp and bivvy will do. I keep the cooking down to one pan and a mug, using more often than not Meths or Wood stove mix, then it is just one set of dry and one set of wet clothes, as I find the more clothes I carry 'just in case' increases the pack weight far too much. You carry more, you use more energy and give off more heat, which equals more sweat and misery. As someone righty says, 'wear your clothes don't carry them'.
The dry clothes consist of a base layer, and insulated trousers and smock. I live in the camp in these and then sleep in them too, which uprates the sleeping bag. Therefore a lighter sleeping bag is carried.
I used to start the day, no matter what activity with 3 layers, base, thick fleece and heavy jacket and within 15 minutes it all came off and then the sweat on my body chilled me. So it all went on again, and off, and on and so on. Now my mindset has changed, I start with a base layer and a windshirt and stay like that most of the day. If it is raining I'll swap the shirt for a jacket and if it's really cold, I walk faster!
I leave off the rain pants unless it is teaming, as my legs also give off heat and they keep the trousers dry mostly. The same goes for shoes, gone are the boots (unless I hacking through dense forest) and I always wear lightweight trainers or boots. A pound on the foot is pound on the back. And once again, less heat is generated.
The bottom line is now my base weight of pack, inlcuding a few toys like knife, lantern and camera gear comes in around 8kg.
Bushcraft gear generally is heavier duty equipment, which weighs more. It is up to you whether you really need that durability. Although the military style look and big packs are popular, when was the last time you treated yourself or gear to that kind of punishment? The balance is finding maximum enjoyment out of what you have. Therefore try something less heavy duty from the charity shop and if it works, don't fix it. The 'just in case' pile is always the heaviest, and strict discipline is needed to eliminate those items. However surely the best bit about the bushcraft approach to outdoor living is being able to adapt and overcome?
I'm sure you'll manage (and enjoy it more) with less, you just have to work out how!
