there are already converters online (i wrote a incomplete one as a neovim plugin for fun https://github.com/pynappo/hyprlang-to-lua.nvim) and reportedly LLMs work fine at it too. At the time i wrote my converter there was already a couple hundred configs i could search through on github to see what people did
Thinking I'll wait as long as I can and then just get an LLM to translate current config to lua once the internet has been seeded a bit with examples
