Just an idea I thought I'd throw out there: if you like the idea of an Anti-Paladin, why don't you use the DRK class as a "base" and effectively play one? Rather than cling to the existing classes and jobs, you could mechanically be one thing while ICly being another. Then you really wouldn't have to worry about the stigmas of being a DRK and not from Ishgard and whatnot.
Since both are tanks, you can dress up your DRK in Paladin-looking gear (minus the ACTUAL PLD gear because of job restrictions, of course) and still call yourself a Paladin. Then you just have your character use more... aggressive magic or what-have-you rather than the Paladin's usual healing set. Perhaps learned from a brief stint at the Thaumaturges' Guild - or perhaps taught to you by friends/family.
Just thoughts.
