Star Wars: The Old Republic Companion Hack? #2 (READ DESCRIPTION)

Hello all. this project is a strange one but I will need someone who is very familiar with the MMORPG game Star Wars: The Old Republic. Basically, what I am trying to get at is somehow switching your companion to a boss NPC character. For example, I want my companion to switch to the Revan boss you face in the Shadow of Revan expansion. This job is quite strange and maybe not possible, but I am willing to pay very well for it! Please do familiarize yourself with the game before sending me a message, thanks.
