Epic Crossovers You Like That Will Probably Never Happen

FFXIV did one with PSO2. PSO2 did one with The King of the Monsters

Make him a special summon; yeah, I just went way left field with this one...

I'll jump on the Valkyrie Profile bandwagon.

Just roll with an alternate ending of VP2 where Lezard defeats Valkyrie and his own flavor of Ragnarok kicks in. Usual dimensional tears and the like kick in, with the remnants of Lenneth, Silmeria, and Hrist being scattered over Eorzea for us to recover and make one last stand against Lezard and his alchemical minions/monsters. Can wriggle in appearances from the other gods or einherjar to help/hinder the player.

Would basically like a bit more than Nier raid when it comes to storytelling and world building. If it actually involves unique areas, we could even utilize our own einherjar system (piggybacking off the trust system some).

My crossover pipe dreams are:

Xenogears
Chrono Trigger/Cross
Saint Seiya
Soul Calibur

Well, the last one probably has more of a chance than the previous three. I'd particularly love a Saint Seiya crossover, if only for the multitude of cloths and whatnot that can be used for glams.

Bloodborne

Hate crossovers and every immersion breaking car and flying sperm they bring with them.

That being said. FFXIV version 1. Give us a FFXI WotG type crossover whether temporarily or as a full expac.

[Shurrikhan]

Bloodborne

I'd rather a dark Victorian zone with some unique elements and progression systems than an outright crossover, but honestly... this and Xenogears (again, more as an art style and tech fantasy than an actual crossover) are the only ones here to really appeal to me.

[Videra]

As much as I agree with the sentiment of not wanting any more crossovers if I had to choose one? Devil May Cry. Mostly because the weapon models would be pretty good and if we get outfits, well, hopefully, that would include one of Nero's arms.

Robotech - Because 9S is a wuss. Also, Varitech vs Magitek....
WoW - Because the meltdown in the "FFXIV vs WoW" threads would be glorious, plus we'd get to mock their ugly characters.
SAINT SEIYA - Imagine the glams!

Edit:
And Digimon - Just to piss off Pokemon fans.

Dragon's Dogma.
Will sell soul.

Persona series (Especially P5S)
I honestly think the personas could be great to see as mounts, minions and glamour pieces.
And the palaces in the series could totally be an alliance raid or dungeon.

I would kill for a Jack Frost minion.
