How many workers do you want to take from working our lands to building these fortresses and railroads? Every worker gone is another tile underused. According to the plan, the troops would be scattered. Do you plan to reinforce every position with just 8 units (I'm guessing divisions mean single units) every 6 turns? 6 turns is a rather long time, considering the advent of rails and the size of any sort of invasion army. Many of our soldiers would be dead by the time any trickle of reinforcements came. General Provo's plan is considering that any enemy would even attack our position, instead of bypassing completely.
