Don't think 6 hrs to egmore is possible for intercity with stops during daytime. Will GNT representatives be ready to divert it back to mainline is a big question. They will ask to reroute pinakini via NGNT are u open for such proposal?? Turnaround time in BZA maintenance time at PDY not sufficient 5 hrs is too low the effective time available is just 4 hrs according to your timings. Some trains which are introduced to benefit local travellers serving office goers and business travellers should not be extended to other places.
