I do not have the expertise to convert individual Landsat scenes to a proper color balanced mosaic. So, as an alternative I am trying to convert the already available Landsat Geocover global seamless imagery from NASA. This dataset has been created from Landsat EMT+ imagery from circa 2000 to 2003.
