What are the thoughts on allowing this? I can think of several valid RP reasons for wanting to rescue certain mobs. Most notably, cabal raid situations. I can't see too many ways rescuing a mob could be abused to do things in favor of a character, I mean, all I really see for people who do it are drawbacks. Why not let the people willing to risk their lives for their mobs do so?

Sounds like a good idea to me. A bit silly and not extremely useful, but a good idea.
