My suggestions:
1. Shift SBC CAPE daily Island express to YPR and route it via SMVB. This will free up one platform for a Bangalore to Mumbai SF in those Platform slot.
2. Introduce a SMVB BIDR SF daily via KLBG.
3. Run MAS UBL trains via SMVB YPR bypass and speed up by another 1 hour minimum.

more... Run a MAS MAO triweekly via KPD SMVB BAW HAS (Dep MAS 1530 SMVB 2200 MAJN 0715 MAO 1200; MAO dep 1530 MAJN 2030 SMVB 0530 MAS 1130).
5. Run a SBC BGM express via BNC SMVB BAW so that crowding in SNC and YPR gets avoided. May be slightly longer by 10-15 kms. When you are running SBC YNK via BNC, why not a link from BNC to Tumkur side?
