I am from Kerala & work in a rather cosmopolitan atmostphere where I get to interact with all kind of people from everywhere. I haven't seen the kind of hatred you try to suggest among people. More over, if tamils hate keralites, will they come to Sabarimala & other places here? Keralites go to Rameshwaram, Kollur etc. As long as the Hindu roots remain, there is no threat to India. Why a Kashmiri Hindu feels Rameshwaram as a holy place? Same way, Tamils are as devoted to pilgrim centers in the North.
With resurgent Hindusim instilling a sense of unity among Hindus & a pride in being a Hindu, I would advice you to stop dreaming on something which is not likely to happen in the foreseeable future.
