Because of this would you be okay wiht adopting swahili? I personally see that as a loss for nilotics as that will probably spur your assimilation into the niger congo sphere. However, hopefully swahilization in south sudan is unsucessful.
Adopting Swahili would be a terrible mistake as it would only serve to gradually chip away at our identity and have us integrated as junior 'partners' -> a Satrap State; I also think that we would be subject to mockery as we learn their language; this would be the linguistic equivalent of hazing.
