Can the Business Rules UI be externalized from the MWS?

We are in the process of building a Process based application using Angular which shall be hosted on the MWS server. One of the requirements is the power users of the application need the ability to update the rules at runtime. We would like to keep the users within the Angular application rather them having to log out and go into the MWS (I understand that we can restrict the options which they see).
Is there any way we could use the Rules in the above mentioned context?
We are using version 10.3.
