ReCoded and 358/2 Days made fine cutscenes for players to comprehend without playing the actual games. Not to mention those games were criticized for level design, combat, and being unfit for the consoles they were on.
While remaking them would be interesting choice (considering how the battle system didn't work well with the DS) it would be a waste of time, especially fans bitching about deranging from KH3's production. Not only little interest, but KH3's development, and the fact that they're considered the least important games of the franchise (even by diehard fans who don't consider them as spin-offs). It just fails to work out.
It's an interesting concept. I believe people should leave it after KH3 is released.
