Sir, while I will wait for the Moderator's reply, let me put in my bit here. Unless this is an independent website, the PNR status fetches the query from indianrail.gov.in PNR status. That allows only one entry at a time. Thus I don't think (I CAN BE WRONG), this would be feasible.
Your suggestion is good, and let's see what the Moderator says..
Good wishes.
