The Saudis and Emeratis did think of that as a back up to tankers but there are limits.A more reasonable soluction would be multiple pipelines from The Persian Gulf to the Red Sea, entirely within Saudi Arabia. Being a fixed structure it would be vulnerable to attack, but being entirely on Saudi territory it would be much easier to defend than moving ships in the Persian Gulf.
It would be expensive, and take a long time to build. Everybody wants quick solutions. The only quick one is paying off Iran, also expensive.
