Before Russell Watson became famous, when he sang in the working men's clubs in Manchester's suburbs, his bill said "Russell Watson - Everything from Meat Loaf to Pavarotti", so I'm sure he could've handled anything. And the band could've just been different, and that doesn't mean shit. Maybe they'd have ended up even more amazing instead.
Considering Slash was in a band called Guns N' Roses before Velvet Revolver, and two of the other members in the band were also in Guns N' Roses (Matt Sorum & Duff McKagan), they wouldn't been like they should have been. They are a hard rock band, and that's what they were meant to be. Just because Russell Watson sang Meat Loaf, that doesn't mean that he was capable of singing hard rock. You can sing hard rock songs in an opera voice if you want to, that's probably what he done.
They went for Scott Weiland in the end, and that was probably a great choice - but he became a drug addict in the end... They have auditioned for over 1,000 singers over the years of their existence, so I wouldn't be surprised if Slash got desperate.
