Moi does not currently have any tools for adjusting an exissting surface while maintaining G2 or G3 constraints. But you can create a blend surface where the blend surface has G2 continuity between the surfaces being blended.

But I'm not sure how G2 constraints applies to your particular case though - G2 constraints mean controlling how one surface is shaped at its end where it mates up smoothly with another surface. So it's implicit that these types of constraints deal with multiple surfaces, while you only seem to have one surface in there...

If you want to make a surface that matches both the yellow and red curves, you could try doing a 2-rail sweep instead of just a 1-rail sweep.

Select the line for the profile curve, then run Sweep, and then select both the yellow and red curves as the rails, that will generate a surface that goes through both of those curves. It may be helpful to put in a few more lines between the rails to more specifically control the shaping.
