Of course it's possible. Just follow the usual steps for creating caustic scenes:
1. Ensure your materials are properly configured to work with photons.
2. Ensure your geometry is properly configured to generate photons.
3. If you're wanting the mrSun to generate photons GI and/or caustic, use the photon targeting option of the mrSun.

Now, knowing that it's absolutely possible to setup a caustic scene with the mrSun & skylight portals, you have to decide if it's worthwhile. Perhaps simply using a caustic projection map on a light would provide decent results with faster render times, more control, and less hassle.
