Creating a FAR compatibility patch on aeroparts - What are quick/easy ways to produce such?

[RunaDacino]

Hello!

 

There is a user on /r/KerbalAcademy who wishes to build planes with firespitter and ColdwarAerospace. However, it appears they do not work with FAR: using the parts produces the wrong aerodynamic center icon (it has lift) and it causes some nasty aerodynamics issues. 

I know, in principle, how to fix it by looking at my existing mods and how they created FAR compatibility. I have searched the forums, and the firespitter thread seems non-existent and the ColdWarAerospace thread has no mentions of FAR or Ferram.

I am wondering what to do though if, since you aren't the mod author, you do not know how to fill out the chord sweep, chord length and all those details. 
I see that B9ProcWings does not define such for FAR, and simply says "ForceUseMeshes = True."

 

Would this approach work for the aforementioned 2 mods as a potentially hacky fix to this user's problems?
