TallAdam85,
I just want to share a story with you. An instructor of mine relayed this story to me when I was approached by a Jujitsu instructor who was looking to teach at my location.
There was an instructor who did add a different style to his school with that style taught by a different instructor (who I will refer to as the "Visiting Instructor"). At first everything seemed to go well. After a while the visiting instructor started to recruit students out of the main instructors class. This started to build some tension. Later the visiting instructor started to bad mouth the main instructor's style. He said things like its not a "Real" martial art. It has no emphasis in combat. Eventually, the tension was so thick the two could not stand to be in the school at the same time. The visiting instructor was told that the main instructor had "insurance" to cover accidents when he initially set up the arrangement of teaching at the main instructor's school. As a result, the visiting instructor started to stage "amateur" fights. Often these would result in one person being beaten and bloodied pretty badly. To make matters worse, the visiting instructor wouldn't clean the mats. After all, these mats were not his. So he left the blood to pool and stain the mats. Soon students started to drop out of the school for many reasons. In the end the main instructor had to remove the visiting instructor. It nearly came to blows is my understanding. The main instructor nearly lost his business which he worked so hard to build. My instructor mentioned that the reason we should be teaching is to pass on the style the way it was handed down to us. Money should not enter the equation, and my instructor believed that was the motivation for the main instructor to add the new style taught by a different instructor in the first place.
No matter what you choose to do, I wish you the best of luck.
Respectfully,
Master K.
