Is it possible to write a script which opens Blender's existing FBX exporter window?

I’m wondering if there’s a way to programmatically open Blender (2.79)’s FBX exporter UI with Python script.

Basically, what I’m trying to make is a script which, when ran:

• Modifies all the UVs for each selected mesh.
• Opens the existing FBX exporter and allows the user to export the modified mesh.
• Once the user closes the FBX exporter window, for the mesh to revert back to its original state prior to running the script.

I know there’s a way to export FBX in script using bpy.ops.export_scene.fbx, but I was wondering if it was possible to open the UI’s FBX exporter instead.

Thank you so much in advance!
