As for the last paragraph a good example of this is the closing of a contract from an iot device signal. The device signal may be on the iot chain or chain code instance and the contract logic on another. The only problem with your theory is how to do that with a turing complete system. I can send signatues for anything but actions which occur based on those signatures you would want a somethingwhich continues the chain of trust. Im not sure of any way to do this how you are describing while still maintaining turing completeness.
