Red Mage: The one class that will be impossible to impliment

[Tharian]

No, being able to use swords, slightly heavier armor than most mages, and magic, that is Red Mages focus. I have not played Bravely Default, my sole experience with the concept of a Spellfencer class that is not synonymous with the Red Mage class (as it was in Final Fantasy I) is from Final Fantasy XI, where-in the Spellfencer is actually called the Rune Fencer, and is in fact a Tank Class.

EDIT: Apparently FFXI's Rune Fencer also has access to Phalanx, which makes it by default the single most broken Tank Class that was originally designed to be a Tank Class in that game since it also gets Stoneskin and Blink... Unlike that game's Red Mage which was first a Mage Class that the players of the game co-opted into being a Solo-Tank.
