I would love to see it as a Rajdhani train. Problem is - they would have to disallow booking between intermediate stations (as is the case with current Rajdhanis). For example, someone from Nasik would not be able to book till Gwalior or Agra. So, it should probably remain as an AC Exp. and be given a nice name - Vidyut AC Exp. (as fast as electricity :-) ).
