Well, yes, because they're just properties. But unless I misunderstand you, you don't want to do that. The FDM reports the lat/lon/alt of the aircraft coordinate origin, not the c.g., no?

No.
JSBSim currently (the version in in FlightGear, anyhow), reports the position of the CG, since that is what the EOM natively tracks, anyhow. We can *report* anything, though of course, as we have intimate knowledge of euler angles, CG position, and offset from the CG (dynamic) to any other point on the aircraft at any time.
