World of Final Fantasy has a lot of potential subtext to read into when you look at the character match ups, and how closely related their scenarios are to their original games.

A side plot of WoFF is that the Bahamutian Army is kidnapping summoners. These end up being Yuna, Eiko, Terra, and Rydia. But Faris was possibly a secret summoner as well, since she has Syldra.
In this continuity she might also be Eiko's sister, instead of Garnet. And her pirate crew is made up of moogles.

The real birth name of Garnet and Faris are both "Serah" (spelling varies). Lightning also fits into that older sister archetype using a false name. Lightning's little sister, Serah, does make an appearance in the DLC.

When they save the summoners from the Ultima Gate, Tidus saves Yuna, Lightning saves Eiko, Cloud saves Terra, and Squall saves Rydia.

However, I think they were making Quistis out to be a Lenna stand-in.
They might also be hinting at Quistis' untold backstory before she joined the Garden. That is, she should could have been adopted by Trabia royals to replace a dead or missing princess. In the same way Garnet was in FF9
