Definitely Bimbo for Mma. Jill Scott nailed the accent though. Tew tight.
The girl that played the woman with the unfaithful husband looks a lot like Dakore down to her carriage. Perhaps Jim Iyke could play the unfaithful husband? He attempts 'smooth' quite well. Maybe even Yemi blaq if the Director can infuse some life/depth in him and break the monotonal recitations.
Dube's gay character could be played by Emeka Ike
I can't think of a fitting Naija actress for the secretary who was by far the best character in the movie. Adulterer! lol
