Hello, if you are still interested in using Myth_CGC plugins alongside VisuStellaMZ plugins, I have created a compatibility plugin that allows use of VisuStella's combat core alongside MythAtelier's CGC plugins. I have not tested nearly as extensively as I should, since both sets of plugins are absolutely massive, but this is at least what I needed to stop my game from crashing immediately upon boot/combat. The plugin is freely available, if you use it, edit it, or run into trouble, just let me know.
