Hmmm. I'd have to see this run through an earthquake model. It seems to me that having them stacked/connected vertically would cause problems during an earthquake.
Think about those coffee stirrer straws that look like a figure 8 (it's a single straw pinched in the middle): if you hold one between your fingers the range of movement left/right is easy but an up/down movement is quite difficult (and if you push hard enough the straw buckles).
There's usually significant vertical and horizontal displacement during an earthquake. My thinking is that Elon's original design would fare better.
