We could work that out I think, but it'd be a whole thing.
First off, the posts would need to be extremely sturdy and durable to deal with all of the plant growth that would go on around them.
Second, elder saplings would have to mark each of them with special spores to keep the forest from overgrowing on top of them and wildlife from breaking them.
Then, since they're solar-powered, we'd have to plan out a path through the forest that gets sufficient sunlight down to their level (the specs would have to come from your end)
Finally, we still wouldnt be able to guarantee any safety for travelers. While we can make a "best known safe path" and place the spores, the woods are still wild. Some creatures still roam wherever they will, and while very rare, not all of them are friendly to outsiders (or even saplings, in even more rare cases).
