Just for a suggestion, Start at 11.00 AM form MAO (Because after 7.40 there is no trains in MAQ direction till 13.00 except 9 AM weekly exp and 12.40 Raj) and reaches at RMM 6.30 AM. Let it run ahead of 12686 MAQ-MAS EXp from Mangalore onward. So it will be a good ONT connect between Mangalore and Rameshwaram. MAO:11.00 , MAJN:15.45, CAN:17.30, CLT :19.05, SRR: 21.10, RMM 6.30 AM. Since the train is a daily train and have sleeper coaches let the traveler make the full benefit. And keep all your stoppages as it is..
