It would be nice. if this plugin could be added. https://www.spigotmc.org/resources/gkits-eliteenchantments-addon-create-your-own-gkits-leveled-gkits-all-cosmic-kits.77407/
There is one plugin alike it however that plugin doesn't have as much gkits and the gkits are a bit hard to get.
This plugin could be very helpful
