This is mixing different concepts, i.e. import and georeferencing. You
can use i.rectify after importing raster data. RPC is not supported by
GRASS, thus the gdalwarp approach is most probably the preferred
solution. In good GRASS tradition, you could also figure out a
reasonable target grid geometry and set this with the corresponding
option to gdalwarp.
