I am not from Laminar Research; just a flight simmer from down under.
You are in the wrong forum asking your question. This forum is part of Laminar Research's overall site found at X-Plane.com and is dedicated to those flight simmers having problems using X-Plane. Not development problems.
Laminar does not market third party add-on aircraft. Any aircraft made available is what is available with the X-Plane software. If you want 3rd party software or information regarding add-on software then support X-Plane.org which is a dedicated site just for X-Plane users. There is no connection between Laminar and X-Plane.org Totally different businesses.
If Laminar did have a copy of the software or information contained in the software it would be for their own benefit and having had personal contact with Laminar staff I am quite convinced they would not reveal 3rd party information.
Why not ask your question with the developers of the aircraft you are seeking. It won't be in this forum.
