It's 3 caster in reality, Blue mage doesn't count because he's in a world of it's own.
Let's go for a little check of the rest :
7.0 :
Judge with a warhammer could happen, warhammer was asked for ages. But the most known Judge is Gabranth and he wear dual sword. So I think Judge can be a thing, but maybe not as a tank.
Geomancer and Scouting, I'm sorry but that is clearly not compatible. Geomancer, as the name induces, is more related to a caster. I highly doubt that you will smash the face of a world destroying entity with some Bell, doesn't really seems effective for me. Also Geomancer, while being mentionned through AST story quest may not be a thing. Square Enix expressed their wish to create unique classes and not some already seen in other FF.
8.0 :
Green mage as a pure healer ? Dude, Green mage cast barrier and shield. Why would it be a Pure healer ? That makes absolutely no sense at all. Read the green mage description and spells that he has on other FF. It's mainly a support with protection. "Shield" was always green magic.
Description of a green mage :
"As the name suggest, Green Mages specialize in Green Magicks/Magics, which are a school of spells that specialize in buffing allies and debuffing enemies. Spells often associated with Green Mages are Protect, Blind, and the Bar-Spells."
As for the Viking you mentionned, More dual wield class wouldn't be a risk to take, because people want more dual wield class. But Viking, I don't know how they can introduce that at all. Also, this is in term of design is really close to the Warrior how is kinda our Barbarian.
9.0 :
Puppetmaster as a MT ? I don't even know how you'd be able to protect yourself with this. Not many people will see this as a tank...
Selfish Ranged : Cannoneer ? We already have one. It's called a Machinist and he already got his fair amount of heavy weaponry. Putting a cannoneer into the game will kinda feel redundant.
10.0 :
Chemist as a Barrier healer. Come on, be serious... What will he use to shield people ? Skin lotion ? Their isn't a single item in the game that create a Shield, that would make no sense. But as a pure healer, creating cloud of healing, yeah that I can definitely see as a class.
Rune Fencer : Another class really asked for. I can't even remember the number of time i've seen people asking for this. If Judge isn't a thing, then Double sword for him may be a good choise.
11.0 :
Beastmaster : Often people tend to say that it would be a "limited" job. I wonder what kind of kit you can have with this one. Also scouting on this make quite the sense because you need strenght to wield a whip, but you need to be agile.
Blue mage : Will never be a full job, they created it this way, and this isn't gonna change.
