Not according to one of the Rover develpoment engineers:
The original Rover hydramounts fitted were essentially the same dimensionally but the rubber hardness was different for the 3 engine types due to the differing engine weight which needed to be supported.
The 1.8 (blue paint spot) was 115 N/mm
The V6 (green spot) was 130 N/mm
The diesel (yellow spot) was 160 N/mm
These rates were designed to give approximately 8mm deflection due to the weight of the engine.
So, you could fit stiffer mounts to the lighter versions but I wouldn't fit either of the petrol mounts to a diesel as they will be less durable and may sink so low that they sit on the internal snubber increasing noise and vibration. The stiffer mounts will have noise/refinement penalties on the lighter engines but they will work.
