I would be fine with it...
If you don't call it plate mail.
It's plate armor. Plate mail is something very different.
Scale mail, chainmail, splint mail/armor... lets get our terms clear.
There are Plate and Splint Armors and are Plated/Splinted Mail. Lamellar and Laminar armors too, and we could even have Mirror armors. And they can be made from different metals, leathers (both in types and in how they were processed) or bones, and each armor is usually good for something specific, so it's very hard to say that one is "better" than the other.
