Hi,
This is possible, but I'm not sure if its recomeneded. I would like understand more about your use case. Do you need a process for represing those things?
What is your goal of having a process for that?
If you browse this repository : https://github.com/Salaboy/emergency-service-drools-app
You will find similar cases (look for the bpmn files), but there it is justified to have a business process.
Cheers
