Ikea STUVA bed - bed only, NOT cupboard, desk or mattress (Welling DA7)

We're about to dismantle our Stuva loft bed. We're keeping the cupboard and desk but have no use for the bed, end wall, and ladder (grey sections in the picture).
I thought it might be possible to cut the end wall to make two shorter ends. This video suggests just turning the bed upside down and adjusting the slats: https://www.youtube.com/watch?v=vfWvkLOsE8o. (The sides surrounding the matress are level on our bed, not different heights as in the picture.) Either method should be straightforward for a competent DIYer.
It will be largely disassembled, but some sections are 2m long, so you will need suitable transport.
The tall wall is covered in shiny butterfly stickers. They should be easy to remove should you feel so inclined!
We're in Bexleyheath, DA7, just off Pickford Lane.
