Auto generated mutations given model

Is there anything on the roadmap to create a class similar to SQLAlchemyObjectType but for mutations that would take a model in its Input and automatically create a graphene.Mutation subclass that has all the fields in it? The reason I ask is that I am thinking about brewing my own and if its not on the roadmap I'd be happy to contribute unless there is a good reason why this is bad. I think I can create a SQLAlchemyMutationMeta and SQLAlchemyMutation class to take the model from the Input class, fetch the fields in it and pass appropriate attrs to MutationMeta.
