Shaw looks nothing like Anakin (who's supposed to look about 20 years younger).
Uh...ok, even if you go the "replace Shaw with Hayden" route, you still run into the same problem. Now, Anakin looks like he did in Ep. 3, so rather than being twenty years too old, he's twenty years too young. Not exactly an improvement.
So unless you're going to suggest replacing Alec with Ewan, this observation won't work as a supporting argument for the Shaw replacement...
