Don't forget Momiji, she's fairly old as well. Plus, Monica, Sayuri, and Tamaki aren't exactly what one would call younger cutesy girls (heck, even Fiona, Nagisa, and Misaki really fail to qualify as such either). If they can create those three (possibly six) despite not actually being younger cutesy girls, I'm definitely sure that the other cut girls can fit in just fine. In fact, I even can think of a romance trope with the Owner that would be absolutely perfect for Christie's character anyways. Think how Mara Jade and Luke Skywalker got together as a couple in the Expanded Universe, despite Mara Jade initially intending to kill Luke per Palpatine's final command. Heck, for a more comedic example, try Ivana Humpalot from The Spy Who Shagged Me (and for any British people on here who might take offense, that's the actual name of the film). And for a darker example, maybe also how Jason "the Ogre" Skolimski was planning on killing Barbara Kean to ward James Gordon off investigating him, but then decided to spare her after learning she was of a kindred spirit and recruited her instead to his sick philosophy, culminating in having her kill her parents in Gotham.I wouldnt bother tbh, TN isnt gonna add anyone that isn't popular in X3 or VV unless somehow they do another Japanese based poll to see which 1-2 cut girls should return xD plus tbh it's probably a good thing they aren't in VV with how it's handled now, I don't think Lisa or Tina or Christie would fit unless it was the standard DOAX3 game, VV is more suited for the younger cutesy girls. Even Helena and Nyo don't really fit imo, but I think they had them in so they could have a quota met for the older girls
As far as TN, based on what Yuffie stated about the 4Gamer article, both the article's writer and Sakuta D. acknowledged that there's a very high demand for the cut girls (and considering 4Gamer is Japanese in origin and made exclusively for the Japanese, it's pretty obvious from the context that they're not talking about fans outside Japan), meaning even among the Japanese, those girls, not to mention Mila and Rachel, are highly popular. In fact, from the way Sakuta D.'s talking, the only reason they aren't adding them in is out of fear of giving them characterizations that would conflict with their backstories just to romance the Owner, and my email/Twitlonger post is meant to alleviate such fears and even give suggestions based on the past games that if anything would HELP give them romantic inclinations to the Owner WITHOUT ruining prior depictions of them.
Besides, I know they're at least receptive towards fan stuff, since aside from those surveys every anniversary that they issue, I actually addressed that they didn't add in the past birthday episodes in the Jewel birthday event despite claiming they had them, and then I got up the next day and discovered them there, their clearly having added them in due to my Tweet and possibly others.
