I think if you tried it to breed Africans in it, you'd have some dead fish.
Growing out fry would probably work, but seems like overkill when breeder nets are so cheap. The best application that I see for it would to use it as a freshwater refugium by lighting it and filling it with moss (though most fish won't mess with the moss if it's in the tank anyway).
So yeah... not something I'd spend money on...
EDIT - you also need a pump/powerhead to run it as well. That means extra electricity and potential failure.
