Don't do it!
I went from instructor into medic work (paramedic), it was a good move; better money, more flexibility, more secure, better variety, better longer term prospects, longer working life.
Most people move from instructor into another job in their late 20s/early 30s so bear that and the reasons why they might do that in mind.
Also don't think you can make a living being an 'expedition medic', it's really a stitched up thing that rich doctors do on their holidays.
Commercial/remote/offshore medic is different and competitive and you'd need to throw a few thousand pounds at more training (PHTLS/ALS/OSM) and even then with a nursing background some companies won't take you. Also at 23 you really don't have the experience, most medics are in their 30s at least with multiple qualifications and years of experience working in a variety of setting, often alone and in difficult places, and often many are ex-military with plenty of background as well.
If you're really set on it (although you can't have been a nurse very long, are you a commitment phobe?!) why not get a nursing job in Bangor or Fort William, go part time and do more climbing and then see how you feel in a couple of years having got some more experience and maybe your ML and SPA along the way?
