No offense man but Absence of something does not point it to a larger possibility.
What i mean by that is, just look at Isaac, Shadow and most recently, Geno. All of them were absent for months, and led people to believe that they would be playable in Smash (an idea reinforced by the absence and later confirmations of Chrom, Dark Samus, and Isabelle, all NPCs in Smash 4 that were absent in Ultimate until their reveals) but ended up meaning nothing in the end.
It's more likely than ever than Lloyd and MH Mii Costumes are likely gonna come back, and we aren't getting any new Capcom or Namco reps. I mean the Heihachi costume released alongside RYU, a Capcom character of all things, and the MH costume was released way after Ryu's release so those costumes DON'T have to come back alongside a Capcom/Namco character, unlike Geno who was released alongside Cloud in 4 so it makes sense for him to come back with Sephiroth.
I could easily see Adol Christin coming to Smash, and having Lloyd and MH come back in the Pass alongside him due to both Lloyd and Adol being both RPG Sword Heroes, and Adol and MH being both Swordwielders (which i know is a very shallow reason to have them being paired together, but hey if they can bring back Heihachi for Min Min's Pack, i think this one is not too out of the ordinary)
