Probably if you added only a little (the kalamatta or nicoise olives might be good) of something it would work best.
By all means though, try and experiment and report back with your findings
I recently had this same conversation with my mother. We are from the middle east and growing up we had hummus with every meal. I was trying to find somethings to add to my hummus and my mom said basicaly what you said in your post. She refuses to mix or add anything, and has been making it the same way for the past 20-30 years.
In our family we do like to top our hummus with fresh flat leaf parsley, some cayenne pepper and a drizzle of EVOO.
If you are interested in playing around with the flavors of hummus, maybe try kalamata olives, pesto, or sundried tomatoes...
