The problem is that Gravity is already "Force" and can well be used in the same or at least similar manners.

For example, when Glynda shot the purple Dust missiles at the airship, pushing it notably on impact. And to at least some extent it can replicate the effects of the barrier, by modifying gravity to provide a "Repulsion" effect, pushing things away like Weiss's barrier did to the WF mooks.
