Standing too tall - how to fix?

Hi
I have been surfing for a few years on a shortboard in Cornwall, UK and now want to work on my stance as I do stand quite upright. Due to me standing upright every time I pop up it has become second nature and feels natural, and crouching feels very weird. I was wondering, what would be the best way to have a lower stance? Would taking a easy to ride board out such as a soft board or long board and repeatedly catching waves and crouching until i crouch naturally be a good idea? Has anyone else had this and how did they resolve it?
Many thanks.
