Well, just my thought but it wouldn't be difficult for Porsche to put in a GT3 MarkI engine (keep some distance from Big Brother) which would solve the M96 issues. An LSD would not be difficult, nor would a sport suspension similar to the 997S w/o PASM. I don't know whether an aerokit would add that much but if Porsche doesn't do it, someobody will, if only for cosmetics. It could be offered w/o AC and electric windows A roll cage could be an option along with GT3 style seats and belts. I think such a car would be highly "adequate" without significant lightening of panels or thinner glass. I don't think Porsche would ever do this, and I know that if they did it would be anything but cheap.
