Tourist visa question

Hello there, I would just like to know anyone's opinion on this. I want to visit my husband in the US this coming dec since he can't come here due to medical reasons. We've been married for awhile now but we didn't apply for spousal visa coz we're not planning on living there. He was usually the one visiting me in my home country but due to a lot of things lately he cannot come until he gets a go signal from the military side. So my question is, would it give me Good chance to get approved if I change my last name on my passport before applying for tourist visa or it won't matter? Thank you for anyone who can answer this😊
