Lightning Returns gives hints to FFXIV: ARR Jobs coming? (Maybe?!)

[Enkidoh]

I don't see how it is far fetched

SE openly admitted that people working on 14 and 13 were talking and giving one others stuff for the others game

That's not entirely correct - the only true FFXIV reference in LR:FFXIII was the inclusion of the miqo'te starting gear as a costume for Lightning (plus Grand Company swords and shields as well), more as a joke than a deliberate attempt to tie the games together, and Yoshi-P jokingly said he'd repay the compliment by "finding some way to allow Lightning to visit Eorzea in ARR", which resulted in the 'Lightning Strikes' event in ARR that became cross marketing. That's all.

The Job garbs in LR:XIII are more of a reference to FFXIII-2 which had WHM and BLM costumes for Serah and Noel respectively as DLC (after all, the Job garbs in LR look nothing like FFXIV AF, pouring cold water on that theory.).
