This is done in the german rating system (DWZ). When nobody has a rating I doubt that you could get proper pgn files from their game for further analysis. Such players usually cannot write down their moves in a proper way. Giving an initial rating to an unrated player is nonsens. If an unrated player plays a tournament he will get a performance which could be used for an initial rating. Of course he has to make more than 0% and less than 100%. A rating system should be conservative. That means, if the rating pool dosn't change the sum of the ratings is constant.
