Personally, when the topic of a new gathering class came to mind, I often think of it being incorporated as a Trapper/Hunter sort of thing. There's already a Trapper's Guild in the lore somewhere, and the chocobo hunters exist, so the prospect made me think of a system similar to Fishing where you'd be luring animals with bait and capturing them for skins, bones and meats. That way you can be supporting Culinarian, Leatherworker and other crafts that require bones in their recipes.

That's not to say that your idea doesn't have merit of its own though. I could certainly imagine it working in some regard, but the idea of having a detector to do the work for you might be a bit technologically advanced. On the other hand, Machinists exist so I'm sure the developers could do something with it.
