Luna, possible to keep him a free 'merc'?

[Kyle]

I've just encountered the mission featuring Luna in Sagrada, and I noticed that if I insist that he turns himself in to the police, that once he reaches the station the player is seemingly able to have FULL control of him. Prior to reaching the station, any orders one issues to him will be ignored and he'll keep right on walking to the station.

I purchased for him one of MoreDread's night ops uniforms, but whenever I place it on him, Luna's head disappears entirely. Now the same thing will happen if it's done to Benecia UNLESS one has installed MoreDread's mod that was specially made for her.

Luna has GREAT stats for a potentially free "merc," and I'd certainly like to keep him if it's doable.

So the questions are these:
(1) Is it possible to keep Luna in one's pool of mercenaries indefinitely (that is, until he's formally turned in by the player to the Sagrada police)? If this is attempted for too long, will it result in a bug?

(2) If it is possible to indefinitely keep control of Luna, how could I go about fixing his invisible head?

Thanks in advance for any assistance!
