[HELP] Plane model swap

[Makoniel]

Hello there! 

I'm trying to swap the plane models between carriers, so that we can have more historical/pleasing loadouts on them carriers. 
I tried the basic swapping/renaming of files, yet it just ends up in infinite loading when I select the carrier. 

Do someone here have some knowledge of a swapping procedure? What tools to use, what things to modify? 
I saw there are some strange files, .anca, that I assume are the different moving parts of the plane, landing gears, payload, etc. Are they what prevents me to successfully swap? 

Thanks to the ones that would want to explore this with me!
