All good with the story-line and experimentation. I am glad that you liked the movie.
I am against for Shahrukh to experiment with his young self. He better keep himself doing his job age appropriate. It looks so over the top when he acted out the younger part. Also, Rajkumar Hirani mimicked the way he made other films but he needed a star who is not Shahruk. He is too big a start to get into the character that was portrayed.
It was a good show though :)
