Not without a bunch of work. Its a block which is part of the world. One version is the broken one the other is the fixed one. I don't see any value in it either, you can craft your own work bench, unless you like to play as a nomad?
The right way to do it would be to just have random events that break them again, and if its broken, sure a fix it quest would be first come first serve.
Would be cool though...
To be honest I would like to see more love for the traders and trade posts. I am not sure if you are planning on adding factions or something similar at some point but having the trade posts be at the heart of that could be very cool.
What if the traders could be some kind of world boss, with defenses and maybe some helpers if attacked and damaged beyond a certain threshold? And it should be such an hard encounter it would be near impossible to do alone on a maxed out character. And every trader has some uniqueness to his abilities in battle, like one spawns some guards, another a pack of hounds, then one simply knocks you out and throw you out of the trade post...that is if he can catch you.
I would also love to see more npc’s in the trader stations. Maybe a hillbilly kinda type that tends to the crops and works on an old truck that could stand between the trailer and the fence, I picture an old type American pickup truck, light blueish with rust and dents.
And maybe a motherly kind of type inside the building that could run it as an inn, where you could pay for lodging, also on horde nights but then with an insane price tag for the added defenses and a salty trader that yells at you if not performing well enough in the defense of the trader station during an enormous horde. Maybe with the possibility to man heavy stationary guns (M-60) on the walls as something of a mini game kinda thing. You would have to participate during horde night of course, or risk getting booted during.
I would really feel the added immersion of having "life" in a trade post. A trade post could have 3-4 npc’s in addition to the trader himself. And each could have their own quest lines that could lead you into danger and glorious rewards. Things like item retrieval, kill someone turned zombie to put them to rest(a dear one from before the outbreak), scavenge for supplies(different types, medical, food, drink etc) and crafting missions spring to mind. Could even have different rewards for different outcomes. Like a crafting missions where they need shovels. Craft 5 shovels. Stone brings this reward, iron another and steel a third and best option reward.
Or even protection missions, protecting the trade post from bandits outposts nearby or bandit raids. And transport missions to move supplies between the different trade posts within the same faction.
And speaking of factions. No faction change should make permanent damage and everything can be rectified, it just takes longer, and you would have to side when factions are in conflict. + with one gives - with another. The factions having some kind of small hub city, shanty town style, from where they control their traders / trade posts and routes could also be a nice addition.
And say you actually manage to kill the trader and his helpers, and that is a mission from the faction you support. When the battle is done, you would have to go back to where you got the kill mission and then protect a caravan of people that move towards the trader station to take it over. This could be a timed event where the faction whose trader station you just wiped out catch wind and also dispatch a caravan to go take the station back. The choice is yours, stop the caravan by killing it off or protect your caravan and risk getting there too late.
This would also open up for some new quest events with helping rebuilding the trade post for the new trader. Like gathering wood and crafting wood logs for the fences. Gathering scrap, fixing up the generator and workstations. Finding schematics and soldering tools to fix the vending machines...
...but I ramble on ... the question was really: Will there be factions?
