I'm not sure the comparison with Drama Fever (or even Crunchyroll) is fair. There was an enormous market of people looking for Asian content (as evidenced by the fansub scene, and Asian-themed conventions worldwide), which made the bet much safer. An African Drama Fever would probably have to create its market to reach such a stage.

That said, it's a good idea, a big bet, and I sincerely wish you the best.
