Readable Books/Magazines and their Retail Displays

Hi, I'm fairly new and I wanted to try recoloring one of the base game (readable) books with comic book covers to sell them in a comic book shop project. That was no problem but when it comes to actually displaying the recolors on retail surfaces (that force the book into the stand display), the recolors revert to the base game book's display. I can recolor the book's display stand object, but could anyone guide me as to how I would link the two objects together - the recolored book changing into a recolored book stand display when put on retail shelves? I followed user anska's work as she was doing something similar but I couldn't find anything concrete to help me.

Thanks.
