Noob Question- RetroBeast and KinHank

[Madmax2040]

First let me apologize about being a total noob.  I just downloaded LaunchBox and bought the BigBox premium license.  I really like the videos I've watched showing the layout and ease of adding games.  (Yes I tried searching the forums but didn't find what I was looking for)

Here's my noob question...  I have the RetroBeast 2TB Lightgun drive as well as the 12TB KinHank drive.  They obviously are pre-setup with all the roms, emulators, artwork and everything.  I really don't like the Hyperspin setup, and the RetroBeast is almost impossible (to me at least) to add additional games or systems not already included.  Can I import everything into a new LaunchBox install on a seperate drive, such as the artwork, emulators and everything or just import the roms to the appropriate system folder and let LB download everything?  
As far as the RetroBeast, I like the Lightgun apps that basically setup whatever gun you have and then you're set.  Since that's not a rom, how would I import that into it's own category/wheel selection?  

Basically I don't want multiple front ends/apps and want to make navigating and loading all the games I have as easy as possible for my kids as well as have all the games available from one front end like Big Box.  Oh, I'll be using this on an AtGames Ultimate Arcade Legends using the arcade control panel, but would like to be able to use game controlers for console games and a steering wheel for driving games.   I know...  that's a lot to ask, but first I just want to consolidate everything to one drive and use LaunchBox/Big Box.
