Andre, anything is possible if you have the skills and the ECU is not locked down. From various chats with Cain of Wolf Performance I doubt it is a practical approach on the Sigma in a Morgan. I probably would be simpler and easier to have a complete replacement ECU which comes with a standard mapping to start with for the Sigma and then to remap it for various types of driving such as normal, spirited and track, then be able to select these at will. A professional company that markets ECUs would be able to help, mitigating be worth chatting with Cain.
