Interesting question you have there! Let me tag all the @power_users here who might help you out with that one! @cjquijano, have you done such a simulation before?
This is going to be a parameter study in any case as there is no rule to immediately give you the perfect design. You have to create different models and test them - there is no way around I would say. On top of that you have to make sure to create a smooth, producible and aerodynamically suitable design.
All the best!
