I mean I could see this working for Rumbaugh but the rest feels needlessly tacked on. I get shipping items for merchanting XP though

In my opinion this would make sense for Rumbagh and Svim tasks as Merchanting and Sailing go well with the theme, even more so if the game would direct Svim tasks to sea adjacent towns while Rumbagh more inland ones.
Ramparte and Heimlich tasks I feel could remain as they are now, they do make sense and involve their respective skills in the process already.
That leaves Brico and Alesi which I feel do not fit this type of task you are suggesting but the current task types are not a good fit either.
