South Africa Revolt as Dutch in treaty

Is revolting to SA as Dutch a viable strategy in TR 40? For those that do not know, you can make 30 courier des bois after sending a card. You can also get a 3rd factory. The best part is you can send a card infinite times that gives your units 5% more health. The longer the game, the more powerful SA gets.

With an 80 vill economy, 7 upgraded banks, 3 factories, and an infinite hp card makes this revolt tempting instead of going to imperial age. The only thing im missing is 2 extra banks, the capitol food card, and imperial unit upgrades.
