Yeah nah, not gonna happen.
That would require going back and diong things to complete something.
And as we all know with the prime examples of Viera and Hroth they are not willing to do so.

They did in SB for SAM and RDM but stopped ever since ShB.
Sure they gave some out Thordan EX weps but only cause of TSR dropping.
They even did some of the missing glowing Trial weapons that didnt exist in EW.

But with how lazy and unwilling to put any effort into FFXIV since DT they became the chances of something like that happening again are basically zero.
We are still missing some glowing weapons from even MSQ trials in SHB and I am willing to bet we will never get glowing EW trial weapons.
