I seem to recall that at some point way in the past used to be able to rearm planes at vehicle fields, it was tricky but it could be done. and also for awhile there there used to be aircraft you could spawn from vhs.
I wouldnt mind seeing Vehicle hangers with limited aircraft similar to CVs, say HurriIIc and IId, A20, IL2, 110, P47s, P-38G, maybe P-40, P-51B. Use reventments like hangers, put 3 or 4 around the VH, they could be pretty soft targets
