I am not an expert in electrical supply grounding, but the isolation of the isolation transformer would be one issue. Not just 240V, but under fault conditions including a nearby lightning strike raising local ground potential.
Also, you don't want two different 'grounds' within the same room so everything in that room would have to be run from the isolating transformer.
