I have some destroyed trader POIs in my modlet. You can take any map and (before using the map) with some quick editing replace traders with those alternative POIs. But I see now you want traders, just not missions. (Your msg rolled in while I was typing.) I don't have an answer for that.
Yah, I used to think the traders were dumb, but there's nothing else to do with all the garbage loot. Otherwise it's just gonna build up to infinity. All I really want is to get rid of the missions, because the last time I tried making a server the carebears just grinded missions all day everyday. It was the most efficient fastest way to level up and get loot, but it ruins the game because nobody wants to explore or build or interact.
