A long time ago, I managed to turn a Bandit Marauder into a follower, but there are a few problems with the process should I dismiss them:

* They return to the place they were spawned at, and not an area I could designate, making it impossible to find them again.
* They not only revert to their default kill-all-non-bandits programming, they lose the mercy invincibility intrinsic to non-essential followers.
* Their "default" outfit that can't be removed happens to be fur armor, so I can't give them other outfits unless it's also armor.

If someone is up for the challenge, I'd like it if they could take my erzats follower and recreate them as an actual follower with all of the above problems removed. There's a few other things I'd like done, but I'll hold off on listing them until someone offers to help.
