Long story short, we want to be able to give wyvern a the ability to dive. The base wyvern class is currently a child of the base dino class. I would like to make it a child of the diving flyer class, which itself is a child of the base dino class Is there a way to slip that diving flyer class in as the wyvern parent class without hav8ng to recreate the entire class?

This would only be possible if making your mod as a "Total Conversion" but Total conversion mods are largely considered a non-starter in the community because it generally breaks compatibility with most other mods.

With normal mods, changes to pre-existing classes that you make in the devkit will not be reflected in the live game. Core game files are excluded from cooking and would not replace the real ones in the live game even if you managed a way to force it to be cooked and packaged with your mod.
