If this is a one time issue (that is, you don't need to automate it),
you can use the following:
CoordinateReferenceSystem crs = CRS.decode("EPSG:3395);
System.out.println(crs); // this will print the WKT definition
String newWKT = "..."; // modified WKT definition with new cent. mer.
CoordinateReferenceSystem crs2 = CRS.parseWKT(newWKT);
Hope this helps
Cheers
