Remember, Bond didn't exactly look like Brosnan in GE64, too.
Also hands were the same in Multiplayer for every character.
So you could say we're true to the original with these things.
Rather think of this as the essence of what James Bond looks like, not only a certain actor.
And it could be far worse, he could look like Craig.
Same for the rest of the characters, you recognize who they are, but they are not 1:1 copies of the actors who played them.
Still better then the GE Remake where the characters were not even close to the originals.
Hands are also a more complicated task then you'd imagine.
Not only that we'll need to add different hand models for each character (they also differe in clothes), but also there are certain things like the Bond Watch used for detonating mines, that needs to be considered.
Would it even be plausible that every character has the same watch (well... maybe they come bundled with the remote mines), or should all characters beside Bond use other detonators?
As you can see many things to considder and i only scratched the surface, there are much more things that can be an issue e.g. animation, different arm sizes (male, female, clothes).
But i ensure you, if we do different hands at some point, it'll be done right.
