Good advice except for this. Spaceplanes are very sensitive to drag. The closer you can get your CoL to your CoM while maintaining stability the better. This requires less angle of attack and less wing area to remain at level flight, resulting in less drag. If you have your CoM in the center of your fuselage then there's no problem with having a CoL right on top of the CoM, the tail plane will easily dominate pitch torque. In fact, I prefer my space planes have a CoL in front of CoM at low angle of attack, that way it will naturally tend toward nose up and require less control surface deflection to stay at level flight.
