[LT] Refluffing Mail and Plate as Plate over Mail?

[CarrionPeacock]

As far as I know, the Mail and Plate armor is a mail with many small plates, like a scale armor with mail backing instead of cloth or leather, and representative of armors from eastern europe and middle east.
Would I break anything if I instead treated the Mail and Plate as the transitional period armor with larger iron plates strapped on mail and then apply the rules for Heavy Plates?
