Troy X-3 and X-5 Coils on a Cortes

I know that Tesoro made the Troy X-2 and that the X-2 coils can be used on Tesoro umax machines like the Cortes.

Is is completely out of the question to use coils for the X-3 and X-5 on a Cortes?
...I know that this post is old but felt that I had some info to add....Some people may not know that although the Troy X-2 was made by Tesoro....The Troy X-3 and X-5 were made by Fisher so the coils for the X-2 and X-5 are Not Compatible with the X-2......Joe
