I don't know if you are translating from this site, but this spanish site has a few good omegaverse mangas like Mitsuketa Boku no Omega-sama, Ore no Yuugaina isekai, Antimoral omegaverse and Romantic Lament. It also has some complete mangas that are unfinished in english like Kiss wa Tsugai ni Hizamazuku or Kisu wa BAN ni Hisamazuku (name in Qvfamma) and Kimi to tsugai ni narenai ryuu.
Just a fair warning but gvfamma hates
it when people retranslate their stuff ( they even have a warning on every translated chapter that they don't like it)) and they have made their site private many times because of it. I know you want to help English readers but translating more is at the risk of them closing again.
This manga is also good. The story is about idols like Maku ga Oritara Bokura wa Tsugai.
It's a pity but unlike spanish i don't understad. I found in the stte Liqueurs
