LTT KCVL SF EXP (22113) looks best bet for me you can board from THANE if at 5:17 PM and reach KYJ next day late evening around 8 PM. This is the fastest option.

For Return on 02/01 from KYJ to Mumbai, same Kochuveli- Mumbai LTT (KCVL LTT EXP (22114) is good for early arrival around 7:30 AM next day at Thane but Departure from KYJ is odd time at 02:32 AM else you can opt for Netravati with Departure from KYJ at 11:10 AM and reaches Thane at around 4 PM...
more... next day. Other options are there but you need to get down at Panvel and travel to Dombivili.. If its ok then can consider that also.
