Yeah I'm here for lolz.
I read your paper by the way, I couldn't see anything erroneous with it other than not mentioning the fact that the spacecraft's orbit would have the barycentre of the Earth/Moon system at it's foci. It is quite a large difference relative to Earth (over 4000km from the planet's centre), but I guess this would come under the 5th simplification about the Moon's gravity.
Actually, elliptical orbits around a barycenter are only valid in 2-body problems.
The Earth, Moon, spacecraft situation is truly a 3-body problem. If we neglect the spacecraft's gravitation, this might be called a "constrained" 3-body problem. Regardless, it means you need numerical approximations - the motion can't be solved for explicitly (no matter how good you are :p )
Kami's paper is actually a 1-body derivation; it assumes the Earth remains motionless at the origin, and omits every other force.
Anyway, please continue with your lolz
