Vaylen pairing with technology

in Faith Conquers, one of the naiven escapes a dead host body and climbs into one of the Iron where it couples with the machine and takes over the power armor for a scene.

there aren’t any rules for this in the BE book, are there? or am i missing something. i thought there were, but i can’t find them. any suggestions on how to go about doing something along those lines?

Theres a Robot-Psychologist PC in my game. Can’t wait for him to meet an Aeumifesh!
