Even prior to the Aerovan entering quantity production, Miles had ambitions to produce multiple derivatives of the type. One such design was a specialised aircraft for the air observation post role, intended to be operated by a four-man crew and featuring an enlarged glazed canopy to provide an all-round view in combination with a glazed rear fuselage section. Work was also undertaken on a flying boat derivative that would have had a single-step hull, keeping the rear freight door above the waterline with the assistance of two stabilising floats carried on outriggers set on either side of the hull. Both designs would have retained significant commonality with the standard Aerovan, sharing the wing, tail, and powerplant arrangement. Production of the Aerovan was abruptly terminated during late 1947 as a consequence of Miles' bankruptcy and subsequent dissolution.
