When we designed ours, keeping the rear seat was part of the criteria. Otherwise, yes, that is going to work as well, if not better than just a simple bar across the rear. It is my opinion, however, that if you ran the bar across the towers like I have it, then also triangulated it to the floor that this would yield the best results as you would then be controlling the flex further away from the load point. The argument could be made that controlling the flex at the load point would prevent the flex further out from happening, but without testing it is hard to say, and the differences are probably negligible for our purposes.
