The thing with that is it wouldn't necessarily be what they had in mind way back just after X2, nor would it reflect how a finished movie version would look. After all the fan blabbering for two years, they might be influenced to alter what they had in mind just so it satisfied what some of the complainers want. Then the complainers and whiners would say 'See, their movie would be so much better' when a comic is not a finished movie and it wouldn't necessarily be the 'pure' version they had in mind way back when.
