I run sites that are in the Latino niche and have been online for the past 6 years. I have found that within this niche that while it is true that there are dark skin Latinos (Dominican's come to mind) that my members expect the stereotypical Latin look in that dark is OK...but not the "African American" look...that would be for a black or ebony site. Therefore, I do NOT mix and match the two niches. The main reason is that most of the guys who are into one or the other have plenty of sites that will supply 100% what they are into and they will therefore subscribe to that (those) sites rather than sites that try to cover BOTH niches.

I would stick to what your current site's core is about and if you find that you have enough content then create a new site for that Latin content making it pure for that niche.
