Honestly, I grew up with the PT, so I'm used to seeing Hayden. However, I can imagine an Anakin similar to TCW, since he fitted more of the Anakin that was generally on everyone's mind, both his image and character.
I have seen other people try to reimagine Anakin something more like a younger Sebastian Shaw (both here and here). I do find it interesting and I think it would be awesome, but I'm not sure how it would work exactly.
