Lest we forget there won't be a new Bond for at least 3-4 years as Craig is signed for the next two films and is indeed working one of them now (SPECTRE).
I love Idris Elba! That said, why not launch him as his own character in a new set of films that could branch off the Bond series. That way he is not constrained by the way Bond is characterized and can create a wholly new character and make it his own. Let's remember that after the enthusiastic reception Michelle Yeoh received as Wai Linn in Tomorrow Never Dies that MGM actively looked into developing a film focused on her but it fell through - partly because she was already attached to Crouching Tiger Hidden Dragon.
