Let's look at some facts:

A) The Lightning Strikes items were placed in a promotional event that ran three times. Those items were added to the cash shop after months of request and complaint threads.
B) The Advent Cloud, Wild Rose attire, and Zidane's gear are from veteran rewards.
C) The only likely event this might happen is for the FF7 Remake crossover that we already know they will do.

The only other possibility for this item coming to the game is the cash shop. Having said that, I don't think you should ask for it to go straight to the cash shop either.
