Obviously I've seen the artwork, I recently commented "Awesome! Thanks!
" on one of the pre-production art pieces posted above that I hadn't seen before, and I posted some pre-production art myself. No, it doesn't look like Batman. I've done a lot of research on Superman Lives, read many interviews with the filmmakers, and have never read any of them say it looks like Batman.
Superman being in a weakened and depowered state upon his resurrection is actually faithful to the Death of Superman, Funeral for a Friend and Reign of the Supermen comic book story arc that Superman Lives was based on.
