Not sure how a Mexican-Am would make South Americans see the WTBTS in a better light. Mexico isn't in South America, doesn't have much in common, and guy is from the US anyway. Wouldn't do anything for me.
May do something for the SW USA. Who knows.

Oh, and Hispanic is not Latino.
Hispanics are Europeans. Ie. Spain, Portugal, etc. (Former Hispania named so by the Romans)
Latinos are peoples of the Americas who speak Spanish (also Portuguese & French) as a consequence of colonialism and conquest. Named such by Napoleon.
