That's a no-no too. Pilots can cancel IFR, we can't tell them to (or even ask them if they want to).
To be quite honest, Rules of the Air take care of it anyway. After all, provided you are below 3000ft, clear of cloud and in sight of the surface the minimum height rule ceases to apply, therefore there's nothing to prevent you being IFR below MSA providing you are in VMC. Terrain separation is then - by definition, pilots responsibility.
