Logo Advice

Hi everyone! One of my clients is a small kollel that I created a logo for with a specific shape and unique look. A yeshiva will now be opened under the same Rabbi from the kollel- and they want me to use the same logo, but just change the name in the middle. I think that if they want more room for growth and to not be tied down to the kollel they should do a different logo, maybe same colors. What do you think?
