Creating custom fbx importer from scene importer or built in importer

looking to extend the functionality of either the scene importer or the default fbx importer. to include option for building a custom actor blueprint from pre-made blue print class. i have a blue print class that has some custom components on it that need to be pre-configured in a certain way, as well as there location set specifically with in a folder structure. i would like to automate these steps for the rest of my team, so that i does not cause errors with intrinsic functionality.

the other half of this would be to package it in to a plugin for portability
