No garibrath extension to palasa is not at good option. There are lots technical problem to extened this train to a small station like Palasa, from where even there is no ordinary express. For BBS there 2 new connections recently added. One BBS-PUNE via SC will bypass VSKP, BBS-SHIRIDI weekly ....and HWH-SC also going to to follow BBS route. They are enough.
Dont worry about the train which is running already with peak waiting lists. If they really worry about the SC connecting it better to operate Puri-SBC vacant garibrath to SC,...

So there is no chance increase in coaches.
