Wall stencil question


So I found this amazing wallpaper this past weekend. Decided it was perfect. But then I saw the price tag. Am

wondering if any of your DIY people would take on this as a paint project. If so, does anyone know where I could get 24 inch square or triangle stencils to make this happen. I suppose I could mess sure it out, but it’s on a 17 foot long wall and if it is “off” it will look weird. I’d almost rather paint than screw up the wallpaper with a grid like this. Thoughts appreciated.
