Vocaloid song Meltdown. Possible variant tag change?

In order to sort out the Meltdown_(Vocaloid) images, I made these two tags. I wanted them to be obvious, but I don't know if they are causing trouble for people by being so long and complex? Arantheus didn't like the tag so I PMd to see if s/he could find a fantitle on pixiv or think of another form of the tag, but no reply back. So I wanted to ask the forum.

• Kagamine Rin_(Meltdown/Hard RKmix)
• Hatsune Miku_(Meltdown/nitamagoMix)

Then there is the other one (old tag)

• Kagamine_Rin_(meltdown)

Which was here when the "tag image to vocaloid song" was starting to pick up. Due to Meltdown having more uploads, it was used for Meltdown in general (big and little Rin), then the "Meltdown_(Vocaloid)" replaced it. After that I started noticing people tagging images of the little girl Rin, so I figured that is what it was used for (wiki). To get to the point, should that be kept as such like the Megurine_Luka_(toeto) or should there be a more fitting title? Some artist give their own titles or search tags.

Little Rin

• ロリン Rorin / Lori (the pun) Loli Rin
• 炉心ちゃん Roshin-chan / Core-chan

For Hard RKmix

• 炉心暴走 Roshin Bousou / Wild Core
• Reactor3 (by Nagimiso)

For nitamango

• 炉心融解 ミク / Roshin Yuukai Miku / Meltdown Miku

I've never used these tags, but I don't have a problem with their length/complexity. Using auto-complete from the danbooruup extension mitigates these issues to a large degree.

I don't think it would be a good idea to start using puns and fan-names unless they are absolutely well established monikers for the character variants or are put forth as pseudo-canon by the song/video creators or the original character designer of these variants.

Yeah, the long tags are fine. I can do a /shortcut alias of some sort if needed.

Should I just add the Japanese titles to the wikis then?

That sounds appropriate to me.
