If it were possible to take the original dev team and dev kit and remake/add to Cross with a new release I would really interested in what they came up with. Sadly any sort of remake/addition/new game will likely be some kind of ARPG bullcrap with a shell of a story wrapped up in a high production budget. Of course, they could always surprise me. Octopath was a welcome surprise for us old guys that still love turn based RPGs.
Interesting enough, in about 2008 we were heavily researching Chrono Cross hacking. There's a proof of concept in that allows you to replace Guile with Magus or Magil (for the Radical Dreamers purists), and the mods include new portraits, character models, dialogue, and manipulated techs. We weren't at a point to which we could create new events, though.

We also had written a prologue, which we hoped to release as a small, independent minihack, that took place in 1015AD after the fall of Guardia. It followed Magil, Crono, and several other character trying to stop Porre's world-conquering machine in what I think was the Another World timeline.
A few caveats about what I remember:
-Crono was a main character in the prologue minihack that took place after the Fall of Guardia, in 1015AD. He was a resistance leader and was now living with a false name 'Conor.' It ended with Crono being killed by Garai while stopping Porre's big bad evil machine, but the Home World timeline version of Crono never died and was eventually recruitable in one of the branching storylines (or it may have been all of them) at the Dead Sea.
-Marle, after the events of the prologue, would have infiltrated Porre and risen the ranks of the Black Wind unit. She would have changed her named to Delia. She had an outfit like Norris' and would have eventually been revealed to have infiltrated Porre to take them out from the inside. She would have largely replaced Norris' role in helping get the Hydra Humour for Kid. She was fully modeled and ready for insertion into the game, actually.
-Robo would have been a playable character replaying Grobyc. I don't remember details, though.
-Ayla would have been part of a new, now-mandatory adventure at Gaea's Navel and would have been a mandatory character replacing Leah. She was fully modeled and ready for insertion.
-Lucca was also planned to be a playable character, and she was also fully modeled and ready for insertion. It was revealed that she had died in one timeline but survived in another, and she would have replaced Luccia as a scientist with relation to Viper Manor. I can't remember the details, though.
-Magus would have been a playable character and would have, obviously, replaced Guile. He was also the main star of the 1015AD prologue.
-Somehow human Glenn from 600AD was recruitable, but I can't recall how we explained it. I remember we had him and Glenn from 1020AD would have both had incredible double techs, though.
