The reason for decreasing Gautami's quota to RJY was something different.
There is a proposal to start a tri-weekly to SC from RJY and SCR is just monitoring the occupancy levels. Regarding 12776, it has to reach Akiveedu after 4.30 & BVRT at 5am and this would undoubtedly be an addendum. As said already, this train is seeing last minute bookings. Secondly, i don't think the occupancy levels will increase by adding KVR & NDD stops to Cocanada! Mind you that RJY is just 15/40 minutes (by road) from KVR/NDD respectively!
