User blog:BossDarkseid/Side-campaign could be possible solution to proposed DLC ending idea?

DA:O proved that this could be done. Why not do the same for ME3? It could go along the lines of "New game - *insert DLC name here* - Import ME3 character". We all know it's not possible to alter an ending that's already there, so why not create an Awakening styled alternate campaign that takes place before the final conflict? All decisions, war assets, etc. could carry over. Bioware could work with the fans on creating an ideal epilogue that we would want to see, and The Mass Effect Trilogy could be redeemed. What do you guys think about this?
