Okay, I personally don't see the problem with this, but I thought I'd ask just make sure it's legit.

If I were to decide to switch characters, and just before I do, I went ahead upgraded a friend's base. Like just as a parting gift, blow my remaining om and get a nice new vault for them. Then the next day or so, I switch. Would doing this be okay?

If both characters contribute to the purchase of the base upgrade, then yes, this is okay. But, what you're suggesting is essentially the same thing as violating the "no transferring OM to other players for nothing in return" rule. I could be wrong, but I think you've discovered a pretty big loophole that needs to be patched up!
