Is there any stock J7 Marshmallow ROM which is debloated,optimised and deodexed?

Hello Everyone! I have downloaded marshmallow update on my J700H and now I am happy with the motion and gestures along with the smart features but i am disappointed with ram about 744MB is used by the system.I am really disappointed with battery life.So i was wondering if any one can make a stock J7 Marshallow debloated,optimized and deodexed ROM.I would also like to have a kernel with a lot of features like double tap to wake,drawing gestures to launch an app and along with power saving cpu governors.
