My mother left a significant sum to a local animal shelter. Her will instructed if that shelter were no longer operational, then the money was to go to a specific national animal rescue. Unfortunately, the local shelter was defunct. I called the current operation and asked if they had reorganized/renamed. No, they were completely separate. I told the attorney that I was sure my mother would rather her money stayed local. The attorney instructed me that the money had to go to the national organization because her will didn't allow for a different, local shelter.
You might take that experience into consideration in your wording.
