How on earth could a Garlean WoL even go two steps into the MSQ without getting run out of town, arrested, or murdered on the spot? This would be like a nazi in full SS garb just sauntering around America during WWII.

If your "third eye" is just perpetually covered by your hair and/or headwear so nobody knows you're Garlean, then I don't even know what it is you're asking for other than to just keep playing a hyur and privately RP as a "secret Garlean" like you're already doing.
