The CoordinateReferenceSystem usually need to be specified at GridCoverage2D 
creation time. However you may create a GridCoverage2D with a dummy CRS, and 
recreate again a GridCoverage2D later with all information inferred from the 
first GridCoverage2D except the CRS. Example (approximative):

GridCoverage2D gc = ...
CoordinateReferenceSystem crs = ...

gc = coverageFactory.create(gc.getName(), gc.getRenderedImage(), crs, 
gc.getGridGeometry().getGridToCoordinateSystem(), gc.getSampleDimensions(), 
null, null);
