Because then you can play with other geometries (ie, prismatic) with higher confidence in computed results. Of course wind tunnel, tufts and/or field tested MPG would wrap it all up with a bow on top. Filling an analysis hole is still an excellent contribution to our collective body of knowledge.
By the same logic I may as well CFD a sphere at various Re. I really can't explore every permutation with my old a$$ pc. I took the template for a test drive today...9 hours later it's still thinking. You may not hear from me for a while...

Some preliminary work suggests the template's nose should be pointy like Morelli, and not blunt.
