Please whatever you do don't use the VCCV reclist. It's heavily modeled on CZ's VCCV reclist, to the point that it includes alias types that aren't even valid in Korean for the sake of copying VCCV. So much of the reclist is redundant or not even necessary to begin with. For example, it includes separate CC and_CV aliases for y/w glides (eg, [gy]+[_ya]), but also includes dedicated CCVs for all of the y/w glides with all consonants (eg [gya]). It also makes you record 3 syllable lines for a single CC alias that could've easily been taken from a different existing part of the reclist, simply because English VCCV originally had similar lines with 3 syllables even though English VCCV used them for more than just one alias and used them for a vowel in English that can only be achieved in a very specific context, which has no bearing on Korean. The reclist was clearly trying to blindly copy English VCCV without considering the fact that English VCCV is structured specifically for English and Korean isn't English.
Feel free to DM me for a link to my CVVC reclist if you're interested. My goal in making it was to make an eve-style CVVC reclist that has little redundancy or wasted syllables (as a result there isn't a fixes line length and lines vary from 2-5 syllables). Its not finalized, but its fully functional. Here's the most recent thing I've done with it, although its not a finalized demo
Also, seconding the last bit that nneko said about learning how hangul works. A lot of consonants (and less commonly, vowels) can change depending on what's next to them and this becomes really important when using Korean VBs so that the pronunciation can be correct.
