Change Surname to get Diversity?

hello

So i was brought up in argentina but not ethnically from there and go to semi-target uni in the US. I have a argentinian passport and although i am tanned and can pass off as hispanic, my surname is quite a dead giveaway that i am not hispanic at ALL (european). Since i cant get into SEO as its doesnt let internationals get in, i know i need every advantage i can get to break into IB in NY in the normal recruiting cycle. So i was wondering whether it would be worth it to change my surname to something more hispanic/latino sounding to make me come across as clearly hispanic to HR. Is this a worthwhile procedure - not much of an effort from my side - jsut interested about the potential upside  - especially since i already have a hispanic passport and will still be ticking the "hispanic" box. Will my hispanic sounding surname still be a "boost" in terms of passing across as Hispanic. I really dont want to be doing intervies and HR be like "what you doing here - your not latino at all". Don't really care about the ethics behind it, since i do consider myself culturally and legally argentinian. Thanks in advance
