Ah... I see. But in that case, you're still talking about a Nollywood USA production, aren't you? If it's a US-based producer shooting a movie in the US with US-based actors to be sold primarily in the US, then it's not a "Nollywood proper" movie... even if it's set entirely in Nigeria. These categories we've come up with are meant not to describe the subject matter or the setting of the stories, but the "market" for which they are produced. It can be done, but it depends on the kind of story you're dealing with. If you want to do a full feature like that, then it has to be a story that is almost exclusively composed of characters interacting within an enclosed space. Something like Glengarry Glen Ross or Deterrence or Fail Safe. Or perhaps even most of Reservoir Dogs. You'd have to be extremely disciplined with your lighting and controlled in your camera movement so that we don't see things like radiators or peek through windows. While most Nollywod movies take place in interior settings, the characters do at least step outside into the compound or are seen driving on the road, but you won't be able to do that. You probably will even want to avoid showing characters coming into the room from outside, too. For me, my concern with decorating the interior space would be to avoid going overboard and "over-ethnicizing." The average Nigerian home is not rally filled with an abundance of stereotypically "African" artifacts, so having sculptures and wrappers and raffia mats hanging everywhere would look just as phony. But yes... It COULD be done!
