Would I be an asshole if I change my name legally/professionally and only told my husband (whilst still using my birth name as my "preferred name")?

My parents gave me a super odd name. Like similar to Peter Pepper-Piper kind of alliteration and cringe. When I got married, I took my husbands last name, as it was SLIGHTLY less cringe than my maiden name. Think like Peter Pepperson instead (fuck this sucks that I need to do this anonymously). Still lots of alliteration, and a comical feel to it. It's been holding me back professionally. I've actually had interviewers say they didn't believe it was real and they had to see for themselves. I get so many creeps on social media who think its a stripper name or that I'm an insta-thot because haha, my name sounds funny (idk, men are fucking weird). And I'm tired of it.
My parents LOVE my name. So do my extended family. It's a hodgepodge of family names mixed together to honour various relatives. And yeah it would be cutesy on a kid, but I'm an adult.
Would it be shitty to change it secretly so my resume gets positive attention and not just thrown out and seen as a joke?
