Yeah I'm probably going to do that, too, as I use the white tunic over mail quite frequently myself. I plan to convert these armors, from lightest to heaviest:
- Linen Tunic (Shirt) and/or White Tunic
- Tabard
- Gambeson and/or Padded Cloth
- White Tunic over Mail
- Light Mail and Plate
- Coat of Plates
- Mail and Plate
If you have suggestions for other armors to convert, feel free to post them. Note that I can't really draw, though, so stuff without a plain front will probably not work.
