Hey Tony,
This is an interesting question-- one I've been pondering quite a bit recently. I think it's kind of a grey area-- on one hand, we can never find all the information to build a scenario, but eventually we may find ourselves straying pretty far from the real event we are modeling. My stance is that it's OK if things are not a complete re-enactment, we must distort reality as part of any adaptation. Where things begin to get outside of the realm of RWO-territory in my mind, is when we create missions based on stuff we can't be sure ever actually happened. My rule of thumb is to find a fact or two and center your focus on that fact, if you need to alter things a little to accommodate that's fine.
Off the top of my head, I feel like we could run into trouble with a seaborne mission, since Mali is a landlocked country. As for US and UK, they still don't have any boots on the ground in terms of combat operations, they are only assisting with logistics (C-130's shuttling cargo, arms, and personnel is the extent of it from what I gather), so I'd say you should stick with OFrP. Can you explain a bit more about why you're not happy with the mod? I think in terms of the voice command stuff, you could always consider disableRadio but that may present more problems than solutions.
I haven't yet gotten a chance to try anything out yet, so I can't say for sure regarding Op. Serval, but I definitely think we're still talking about this being an RWO release. You should attach a copy of your latest builds, once I give it a try I'm sure we can figure out if and where things depart from reality enough to warrant thinking about changing it.
Alternatively, if you are into the direction things are going and want to work on this as a solo project, that's also cool by me (I want anyone involved to feel like they have the freedom to do what they want with their work)-- perhaps we could just do a single-mission release based as closely on the facts as possible.
