To tell the truth, so little of the FIC is spent doing circuits that I can't see it would make any difference at all (to your training, or your subsequent instruction, regardless of the u/c configuration) whether you do the course in a tail-dragger or a trike.
On the other hand, if you feel your tail-dragger skills are lacking, and you'd like to hone them during the course, then you can be sure of becoming more proficient during the course. But I'm not sure I would like my proverbial granny/son/wife being taught to fly tail-draggers by someone who wasn't absolutely confident flying them himself only a few hours ago, regardless of the legalities.
