As regards Jake Lloyd Anakin and Hayden Christensen Anakin, no that's not the same situation as the two Fetts.

If one is a young clone of the other, then wouldn't these two situations be identical?

And to me, Boba could have been the young version of Jango. I didn't think they couldn't be, not a bad bit of casting there IMO. Now please don't get all butt-hurt, I'm only throwing in my $0.02.

I would have assiduously stuck to one rule: you never show Boba Fett. Never, ever, ever. Big fucking mistake by GL.
