Could control-surfaces theoretically be used while still under atmospheric drag to help circularize the orbit. You would definitely have to have delta-V to spare but it seems like you could deflect air to produce a thrust (anti-)radially while sufficiently far from the perigee but still under enough atmosphere to get a decent thrust.
