Yes. Let atleast one train run in that available bypass. Say for example Gol Gumbaz can take that route to avoid one loco reversal. In both sectors (SBC UBL and UBL BJP), there are enough trains and BGK BJP travellers can save atleast one hour minimum.
But SWR train bypassing Hubli ?!?!!. Only in my dreams. Had it been any other zone, it is thinkable.
