I think he's saying it's not the extra data per instance of the equipment that's the problem (because seriously, that's trivial to get around), but he's saying that the equipment themselves would need twice as much data to mark the parts of it as shadeable and to determine the color weights and so on for the actual equipment model. This would mean that for every piece of equipment the game goes to render, it's twice as big, increasing load times.
While there are definitely ways around this problem too, it would take much more work than it sounds to alter and convert their data to accommodate it.
However, this is a feature I would really, really love to have. Too much equipment either barely gets dyed due to the dye being on the accents and not the main piece (Spring Dress, Light Steel equips, sailor top, etc), or dying them only dyes half of it causing the other half to seriously clash, or the accents are brightly colored and undyable, causing them to really clash (Sailor bottoms), or the whole thing dyes the same color when you only want to dye some of it (Shaded Spectacles are the biggest culprit here, where dying them dyes both the shades (default: black) AND the rims (default: silver), causing them to look dumb when dyed even if you wanted colored shades).
Can't we like, have this via an option in our system config, where if it's off, it uses the current models and shows only the primary dye, and if it's on, it uses new two-toned models and shows both primary and secondary dyes? That would make me extremely happy, even happier than having new content released or hunts fixed...
