Sailor Uranus and Sailor Neptune were always the hardest ones for my Sailor Moon analogy for this show. I even considered Trixie and Gilda to be them but they've never interacted with each other. Since Lyra and Bon-Bon are practically canon, they might as well be them despite the fact they're background characters.
This is indeed a cute idea (and I see what you did there, as the meme goes). Also, Lyra doesn't like quite as insane in the new version as she does in the original.
lyra looks so happy in her costume x3
