I'm not sure I fully understand the question.

  1. You have an image with its current RPC plus control points, and want to compute a new RPC consistent with the control points? In this case it is possible, but probably requires some adaptation of the package.
  2. You have an image without geometric calibration information plus control points. Control points would allow to map a plane (or a surface) in 3D space to the 2D image. But the RPC maps the whole 3D volume to the 2D image. So control points are insufficient to generate this mapping. In this cases you usually fit an affinity.
