I ran into a similar problem on the Chosen of the Far Realms. The answer is to include a little caveat saying that if you take the bloodline it bars you from taking the class. Which I will now add. Along with the aforementioned scaling of Spiteful Rebuke.
Edit: Changes made. Added the additional fluff clarifying that they may not even multiclass into Malefactor. I don't like doing that, but there isn't really any other options to stop some of these from being ridiculously powered when coupled with the class they're based off of. Then we have things like the Bladechild where it's not dangerous balance-wise for the Swordsage to also be a Bladechild. Heck, taking a Minor or Intermediate bloodline focusing on a discipline they don't have access to could make for an interesting character. But if they focus on disciplines they already have... It's really not worth it. Then on the other hand you have the Chosen of the Far Realms who, if coupled with True Xenotheurgist, could wreak all manner of chaos with their ability to lower murmur levels.
Editedit: Actually... Given the fluff, I think I have an alternative. Typing it now. ... *There!* Finished. I'm quite satisfied with that alternative. Very good. Oh wait. I could add that as well. One second. ... And done. I think that's it.
