It's quite doable, although it may take you two, or more, attempts to get it right.
The primary challenges are keeping your speed and altitude down.
Takeoff is from EGEW on Westray, to EGEP on Papa Westray. There are grass runways, but the video uses the hard surfaces.
You might want to use 09 at Westray, to 22 at Papa Westray. That looks to be the best match per the video.
