Ethiopians fast castle into pike+siege. is it possible?

Hi all. I've been thinking that it is like halb+siege deathball's castle age version especially if you are close together.

Usually you go drush and wall behind to pull fast castle. They respond it via feudal agression like archers, forward, scoutas or mass skirms. You hit castle and immediately make a siege workshop to make rams to kill towers or mangonels to kill army and slowly push forward. Their bonuses allows them to pull off such wonky builds.

• 100f 100g bonus at each age is like a fast forward button. It allows you to buy eco techs or bank in to go up fast. When you reach castle, game rewards you with a mangonel basically (160w 135g)
• You already made barracks for drush so you can create spearmenpikemen™ because the upgrade is free.
• You already made blacksmith for castle so you can armor up your spearmenpikemen™.
• You build siege workshop instead of stables / ranges which costs 25w costs more. You already have +105res from mangonel so it is negated.
• That remaining 65g? Buy food and make spearmenpikemen™ ¯\_(ツ)_/¯
• Blacksmith

Anyways, it is obviously not a 2.5k+ strat but thinking the possibilities is such fun.

What are your thoughts?
