FFXIII event rerun of some sort? Repurposing and remaking the FFXIII-based weapons

I keep checking the Mogstation shop item sales and it bothers me a lot when I see the XIII weapons.

While I'm not the biggest fan of XIII's saga, I did play it and I enjoyed some things from it. It's mindboggling to me that half of the weapon skins we have from that game are no longer worth spending money on them because there's no real use for them whatsoever, and there's some really cool stuff in there.

Even if we ignore the fact that the caster weapons seem to be for the wrong jobs (Or at the very least Binding Rod should not be a WHM weapon), both of them are locked out of use just because one-handed caster weapons stopped being a thing in ARR.
I'm not a fan of the Vega Knuckles, but I feel they should make a normal Vega gun for MCH.
And Blazefire Saber should obviously have been adapted to GNB considering female characters have the Lightning pose while being GNB.

Having said this, I think they should probably rerun the FFXIII collab - or rather, make a new one entirely. I don't think they should give shop items for free again, but I feel a new set of clothes (Serah's XIII-2 dress to match the Starseeker? Maybe Hope's clothes?) and weapons (Like the aforementioned MCH Vega gun) would be cool, and while they're at it they should take that chance to change the Mogstation items so they're allowed to be used nowadays.
I'm mostly bothered by the one hand limitation of the caster weapons, but moving Blazefire Saber to a dual PLD/GNB glamour would be cool too.

I would love to see the event return (obviously with different gear), but I want one handed weapons to work on two handed weapons for glamour. They don't even use different animations, so there is little excuse.
