But it makes no sense, the GLs are supposed to guard a large part of space, it would be downright selfish of themsleves to abandon all the other planets that need their help in order to stop bank robbers in Coast City. Hell thats one of the reasons that the movie sucked. Also the thing that separates the GLs from the other heroes is that they operate in space, otherwise their stories might as well be superman or Flash stories. It also takes away from the adventure and the exploration away from the character. So yes, it is a horrible, awful idea to have a green lantern book that mostly takes place on earth, regardless of which character is headlining it. If there are any good earth based green lantern villains then give them to other superheroes.
