The OP seems to have disappeared.
I'd like him to define "airfoil shaped" as regards a belly pan. Exactly what does that mean? Got pics?
I'd also like him to define "optimal:" If a belly pan is "suboptimal," then what's optimal? Exactly how does an irregular or rough shape become less draggy than a smooth one? Where else in aerodynamics is this true? After all, the fact that a surface is upside down should not effect how slippery it is or isn't.
