Would being a qualified CBT therapist be good experience coupled with some AP experience to get onto a doctorate ?

Interested to hear people’s thoughts on this, I am a lot older than most and being toying with the idea of clinical psychology for a while, I am a qualified CBT therapist and was considering going down the conversion psychology masters route, to then gain some experience as a AP for a year or two to then try and apply for the doctorate. Would the fact of being a qualified CBT therapist working in the NHS be a good level of experience to have as I am heavily patient facing and delivering nice guideline treatment pathways.
