Wow didn't consider that. Although if the Marines really wanted Luffy so much they would have assigned the task of hunting him down to someone else, someone stronger. And remember that they didn't even know if Luffy was alive or not. So even if you're idea is correct, this Task Force is probably not Luffy specific, instead they hunt down all pirates. Also, if he's not hunting down pirates he's probably hunting for treasure. It's what Buggy wants most after all.
