So an update on this bug. It appears that you can only have two of the Maguuma's skins applied, doesn't matter if its just boots and gloves, boots and shoulders, or gloves and shoulders. The moment you apply or attempt to apply the third skin (boot, glove, or shoulder) it crashes the game. Also, as state before, if you apply to equipment then equip having all 3 after the fact, you can no longer log into that character. What is even worse, if it loads the character models in character selection screen, it will cause you to crash as well. As of this post, only way I can get in game before crash is to randomly double click a portrait before models load to prevent the crash.
