I'd say it's not OK, ZJSN's enemy vessels are just "Enemy Vessels". Some of them do have "deep sea" in their name, but according to official wiki they are more likely "alien" instead of "deep sea inhabitant". I suggest leave Shinkaisei-kan for KC use only, create something like Enemy_vessel_(Zhan_jian_shao_nyu) for the ZJSN enemies. I believe separating these two titles can effectively eliminate confusion and the possibility of verbal fights.
