In the second image, I think the tape measure line might be at a too-steep angle in the aft portion and could produce separation sooner than you'd prefer. Do you have the means to build a prototype, possibly of cardboard for tuft testing? You could build it, tuft test it, modify it, tuft test it, and by that means get a better sense of the most likely shape.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
