Oh yeah, this is 100% what I want for the final release.
I've been enjoying most of the companions so far (Shadowheart, Astarion, and Gale are my favorites), and there are some characters that I wish WERE companions BUT the mechanical joy of having a well synergized team with options that aren't yet available is so appealing. I'm glad that there's a method of doing it through 'unintended methods' by spoofing the multiplayer with debug logins but its VERY clear that it was never intended to be used in this method.

In either case, having the ability to have your own CaC army in this game is exactly the sort of thing I'm interested in seeing in the final release.
The conversations between them have actually been decent as well, albeit a little flavorless (and I'm sure that's just from the aspect of it being 'one size fits most' for CaC).
