I'm sceptical whether there is still a chance of her career rekindling, because
a. every season she does fewer important shows: she did Dior, Alexander McQueen, Givenchy, Marni; but not this last season (F/W 2008/2009)
b. although - I agree with you - she's absolutely gorgeous, I suspect the problem is she's too tall and dwarfs most models who are about 5'11; one of them wearing heels has the same size as Eva wearing flats. You'll also notice that on most photos you can't feel her size.
c. I suggest - and have already suggested - that she moves the other way: that she gets much better known always wearing high heels and becoming an extra-tall fashion icon: it's the only way too come back to the spotlight.
