I strongly suggest a regular supperfast train between Yesvantpur to Ahmedabad VIA Kacheguda. Though the route is 175km more than other short routes but it has better infrastructure (2/3 of the route is bouble line electrified).
Secondly, this route will connect many cities with a single regular train - Ahmedabad, Surat, Hyderabad,Bangalore. Please find attached the route and the timings.
Thirdly, you should have 3 (2A), 5 (3A), PC, 10 (SL) as a combination. I bet IR will have good response to the train.
