Why not try flying in sideways with an into wind heading - or gradually cross control during the approach so that as your speed reduces, you yaw further into wind. No airspeed and a downwind turn at height sounds less than ideal.
The wobble when operating with crosswind from the left may be due to interaction of the MR vortices with the TR - typically a wind from 10.30 to 11 o'clock will produce this - the retreating side of the disc will have higher AoA and therefore a more powerful tip vortex than the advancing side.
