Once the air gets to a void,it turns 90-degrees and goes in.It must have a solid surface to support flow.
That's not to say that the outer-lying flow won't make the 'jump' as Hucho refers to it.
In a dead calm,with only a pure air 'source' from the front,we'd have symmetry,but in a crosswind,the windward static pressure would induce a transverse flow through the body void,setting up vorticity as the jet collides with the flow on the leeward side,tearing the boundary layer to shreds and forcing separation.
You'd want to do 'something!' The hole in the body would not allow traditional spoilers to function as a boundary is necessary to capture a locked-vortex.
