I'm guessing, but you may be able to strip the MKC 2.3l EcoBoost down and bolt on all the 2.0l Escape intake, sensors etc so you don't have to change any looms and then get a custom tune done on your current Escape PCM. You may lose some power- if say the intake or something else is revised for the 2.3l- but it could be the easiest path. A custom tune for high octane fuel should get more power than the stock MKC too.

I have zero personal experience but, assuming he swap is successful, from the reports I have read, you might be taxing the transmission beyond its limits. You would certainly need better motor mounts. My 17 2.0 turbo has brutal torque steer if you catch a healthy downshift after the turbo is spooled up !!

The same transmission is used in the 2.3l MKC.
