The malfunctions in the simulator are as per straight out of the RFM, and that doesn't include un-commanded extension/retraction of a servo piston. If there was demand from clients to practise this malfunction then a case could be made to the simulator manufacturer to update the software to do this (= expensive!). I don't know how close the motion simulation would be able to get, it would be a pretty wild ride I expect
My opinion is that these malfunctions should be included to the RFM and also should be trained during recurrent simulator training to the flight crews "SWITCH OFF HYD1" if it doesn't recover the controllability "TRY TO SWITCH OFF HYD2" and hope that the recovery could be achieved.
SIK has this software already in GenHel simulator so it should be very easy to be updated to the all S76 full motion simulators.
