Unfortunate particle timing in the screenshot aside,
I made this by rotating an armor stand with commands such that the glow stick is parallel to the floor and the (future) wall.
I then placed another armor stand and moved it by 0,5 with commands, then moved both of them by about 0,3. Saved both armor stands into a structure to load wherever you want (it's better to select "Remove blocks" if you already have a wall ready and load them from the side/below).
It does look a bit glitchy but I think it can be fixed with better spacing between the armor stands (so that the glow sticks form a line but don't clip into each other too much).
Also in my case I placed barriers under them, so they can be up there.
Alternatively, I think you can continuosly tp them to keep them in place and at the height that you want.
This is all theoretical though, I haven't tested anything yet except this build.
