I would love to see this happen, but only if the wall was built exclusively through the labour of the people who proposed it. The Canada-USA border is the largest unguarded land border on the planet for reasons beyond the goodwill between our nations. Features along it like the Great Lakes and the Rocky Mountains make building a wall impossible. Thankfully reality doesn’t matter to Republicans so they could be convinced to try.
Last time I saw it was on 5g of mushrooms and I thoroughly enjoyed myself.
