Is my name change idea weird?

Long story, but my maiden name is neither my mom or dad’s last name, rather, my mom’s ex husband’s name from before she met and married my dad. I’ve never liked this because, while I love them, I don’t have a very strong connection to that side of the family. Also worth mentioning, I never had a relationship with my dad before he died.


I was recently married, and I like the tradition of honoring my side of the family by changing my middle name to my maiden name and taking my husband’s last name.
Given that my maiden name isn’t a connection to my bio family, I want to change my middle name to my mom’s current last name which is her maiden name (only a 3 letter difference from my current middle name).
I realize it’s somewhat unusual, but given the circumstances, I don't think it’s all that weird. My mom acted like it was the dumbest idea she had ever heard. I was honestly pretty taken aback by her response to the idea. Is this a totally weird idea and I’m just not seeing it?
