Total War Economy

While reading an article about ww2, an idea came to my mind why not Introduce the option of having a full war economy to the game? A war economy is when a country's resources and infrastructure are organized to support a war effort, this includes the mobilization of labor, industry, and finance. Total war economy is when a country uses its full strength. Historically Germany, Japan and the USSR most promeintly adopted a total war economy so did allied powers like the Uk and US, mobilizing their entire economy, manpower and materials for their war effort. So how would this feature work?

For example a player clicks their profile while in diplomacy there they can select the option to issue a all out war economy which would have its pros and cons.

The pros would be that you will recive a bit more resources around 10%-15% more metal, oil, food and maybe manpower for the cost of morale and popularity among other countries. to ensure this feature does not butcher the game. The total war economy option will only be available after a set limit say after day 7, it is not an early game thing and it could have a cooldown timer of say 3 days, 72 hours or more. Also an article will be generated in the ingame newspaper once you start your full war economy, Like when you issue trade embargos so other player will know it too.

The cons, Once you do choose this option your nationwide morale will start to decrease like 5% per day and it is vulnerable to unstability like being unable to prevent revolts and losing your core cities or capital to an enemy will severly damage your populations morale and if being at war with many players at once or invading without declaring war while in war economy will severly lower your global popularity among Ai and other countries. Leading to a higher chance of the Ai going to war with you.

It sounds interesting and might make the game more fun/realistic.

Do comment you thoughts on this. can this be a good feature or will it just ruin the game.
