Two reasons why Statham would not voice Jacob:

1. He is an actor who is known to play in live action films. He only voiced once a character and that's from an american film. Very unlikely he would come to voice an anime character.

2. Jacob is a villain, the type who might damage an actor's good publicity. Many actors would not like to play villainous characters with similar personality.

Aside from this it would be ironic:

Character based on an actor is voiced by THAT actor.

And aside from this, the blond reporter Jason isn't voiced by the person he is based on. (That makes more sense because reporter Jason isn't based on an actor.)
