Yes, it is causally relevant.

Thank you for answering the question. Your answer helps me address your theory more directly. In order to be causally relevant the subjective experience must fall within the causal chain as follows:

brain-state ---> feeling ---> behaviour.

But that is not what you propose, which is this:

brain-state/feeling ---> behaviour

For any given instance of consciousness, you have a third-party observable property, a brain-state for example, causing another third-party observable behaviour. But you also have a second property, the first-person subjective feelings associated with the brain-state also causing the observable behaviour. Your theory makes two causes, one subjective and one objective, responsible for one effect.

You have one thing, an instance of consciousness. It has two properties. The first is a physical brain-state. The second property is feeling. Which property is necessary and which is accidental? You must choose.
