   That should be right. Just some rough calculation:   
   If you wanted to reverse your LEO orbit, you'd need 16km/s.   
   To go from LEO into a highly elliptic orbit, touching the moon's, you'd   
   need some 3km/s. At lunar distance, your velocity would be lower than   
   1km/s (the moon's orbital speed). To reverse this, you'd need 2km/s.   
   Drop back to perigee and brake away the 3km/s from the beginning. Thus,   
   to reverse your orbit with this technique, requires 8km/s.
