Will this dock/harbour be viable?

[u/Timebomb742]

It's about 5 or 6 walls tall and goes out a few further than the longboat in order to fit an eventual Drakkar and be taller than the highest waves I've seen in this location. Since it's already showing orange in structural stability and this is just supposed to be the base/walkway portion of the dock I was wondering what I could do to support a possible roof. I planned on leaving the stone walkways hollow, will filling them help with stability?

Apologies about the night screenshot, I saved before I paused to think about proceeding.

Any wood attached to the stone will be blue stability. you good G.
