RAM $11E4 and adding Gau to a party?

Looking at the "On that day" script, they just remove him from the party. Since his normal WoR recruitment involves simply going to the Veldt to fetch him, that leads me to believe adding him to the party will fix any Veldt roaming.

to be sure, it also un-enlists (as in, removes them from the roster) everybody besides Celes at CA/5310 - CA/532B.
