That is an interesting thought, but I assume that the working ranges of the different appliances are different so there would be some complexities and inefficiencies getting them all connected to a common circulation loop. If there was a thermal equivalent of a transformer used for alternating current, that would be amazing.

As far as I know all the common commercially available heat pump appliances all use the same refrigerants, so it doesn't seem like it would be that challenging.

In cars that have unified heat management the refrigerant cycle is handled as a separate element, with a manifold controlling individual coolant loops to each component. I'm picturing something similar for the home, with a coolant moving heat to and from each appliance using standardized communication to the manifold. There would probably need to be heat buffer tanks, but air to water heat pump systems for radiant heat already need this anyway.
