That's certainly an option. 95% or more of the game will be completely unnaffected by ditching the alignment system altogether. When good and evil are just words used to describe a social construct (morality) then they really only matter to the people that use them. You could just as easily use sweet and balls in their place.
Of course, if alignment has no mechanical impact; or more properly, doesn't exist; then discussing it becomes something of a moot point.
