Folding Plate confusion

[Gothic_Artificer]

Question: Can a Folding Plate be re-flavored to be a Gray Maiden Plate? And for that matter, is the Full Plate Armor able to be altered by special properties? That last one I can see why not, but the first question is the one I’m genuinely curious about.

[RealAlchemy]

Folding plate is a named item, rather than folding being an armor property. This creates issues with modifications.
