Your way is also fine. Please make sure the new landuse of yours are in 
BATS legend.

Have you tried the LNDFUDGE ? It is a easier way.
   1. run the terrain.x (this time LNDFUDGE=.false.)
   2. edit the text file LANDUSE, make the change in this file
      (In LANDUSE file, 1 = Crop/mixed farming, 2, .... 9. Tundra,
       A. Irrigated Crop, .... see Table 1 of RegCM User's Guide)
   3. edit domain.param and set LNDFUDGE=.true. rerun terrain.x
