I honestly think it should be compiled of 3D, and full remakes of 358/2 Days and Coded, with fully fleshed out stories. We know Nomura wanted to remake 358/2 Days but didn't have enough time and settled with cut-scenes. I know it would be a tad repetitive with them being in both HD remixes, but I think this would be a great idea instead of packaging it with KH3, it'll let KH3 have time to shine as it's own title before grouping it.
