As already been said that Llymlaen will be the Goddess of Navigation, I see no real corresponding of them being able to be summoned by the "according Summoner Job" O.o
I would rather say they are like Lore Gods to give the "history" of the world a more appealing effect of Fantasy :)
They can also be imbued into the Storytelling, like if you have a Mission on a ship and its about to crash, Llymlaen might show up and do some nasty navigational things to rescue everyone^^
I wouldn't give them to much meaning though, I would assume they are just there so you can tell something about them^^
Regarding the summons...although I know they want to prevent "traditional" things, I don't asume this will take action at the names of the summoning, because this IS part of FF and just can't be "changed".
Or maybe they will give them other Names, but still the same appearance, like for example the Jobs/Skills in FFXIV^^
But that wouldn't fit IMO, If I seee a little greenish/blueish rat walking around with a crystal on its forehead...I wouldn't like to call it "Green Lantern" or something :/
