I went ahead and used Codex to modify the installer for Fedora. I’m not a developer, so this was entirely GPT. Having said that, the installer is now much more automated, writing backups to an automatically mounted partition on the installer USB, giving options for DE, automatic copying of network info to the installed system, no password length enforcement, no LUKS (not something I need), and all via a single command with some error handling and progress output. It also handles kernel updates now via dnf scriptlet (tested working).
