Our Sprites already work with rpgmaker. Our tiles are 48x48 :)

The Grid is 72x72 so it will allow you to create crazy props for them (e.g. massive wings etc.). You need a lot of space for that.
And this is related to the style of the character sprites which are tall sprites. Not 1 head chibi. The videos and screenshots on our various packs already show them working with 48x48 tiles. If you are exporting Single Character Sheets (3x4) instead of a Full Character Sheet (12x8) you will need to add $ on the prefix of your filenames (e.g. $Filename).
However, we have no plans on ever making RPG Maker MV/MZ RTP-style graphics as they are KADOKAWA's property.
