Heh, not so sure if my mod will work with Requiem, but it'd be neat to at least try! I've never used Requiem myself, so I'll leave the testing to you guys.
Also, let's see if I can finish these bugs today. The main quest is split in two about halfway through with a big choice, and I just finished the bug testing for one of those two sides yesterday. Hopefully the other side will be just as easy.
EDIT:
@R.D.: At launch, Alton sends your companions back to their waiting locations, just like all DLC do. If somebody wants to make a mod to get them in Alton, they can do so. But companions would not work in the main quest (or at least not in parts of it), and Alton is really more about the relationship between you and one of two factions, so where would companions fit into that? Plus, it introduces the complications of the companions not having any new dialogue based on the situation (i.e. suddenly being thrown into Alton).
Again, I'm pretty open about what people can do with the mod. Feel free to add companions in, but I won't support it myself.
