Legendary Seliph

So, I've been thinking about legendary heroes, and right now we have
2 From Sacred Stones
2 from binding/blazing blade
2 From Awakening
2 Unique to heroes
2 From Mystery of Shadow Dragon of Light
1 from Fates/Conquest
1 from Path of Radiant Dawn
And 4 remaining spots
None of this is new information or anything, just establishing a pattern
So I was thinking that if they continue with the pattern of 2, then we could see another from Radiant series (likely Michaih considering her role) and another from fates conquest(these games were cluster fucks, but I could see Azura, Corrin or Xander) aaaand then representation from another game, but because patterns seems to be the topic, we also have to notice
4 red
4 blue
3 green
1 colorless
Which means that either
Colorless gets shafted and we get more red/ blue/green units
Or
We get 1 green and 3 colorless LH
I sadly think colorless gets shafted here and what i'm really looking forward to is...
Legendary Seliph!
Look, he's bad really bad
REALLY BAD
But, he's not in his game! He is a beast with (Divine) Tyrfing, giving him +20 res and I was wondering if you guys could see something like this as an actual stat spread for Knight lord:
Hp:44
Atk:40(56 with weapon)
Speed: 25
Def:35
Res:15 (35 with weapon equipped)
BST:159 (super boon 160)
I feel as if Tharacia776s' return to power should be profound! Though, another sword can could be pretty lame, so to spice it up, I was thinking maybe it could mark the return of Cavs to meta, and to do that give him a unique C skill that allows Calvary units to pass through ditches, but with some caveat (whether its lots of horsies or the only one, could still be interesting)
I honestly do think we'll get a legendary hero from tharacia, because not only is Gaiden the worst recieved game of the series, but even the Remake didnt go so well (SoV) and we've already seen the lack of love to Gaiden, so why would IS start now? They don't have axe units, so the green slot would be hard to fill (green archer alm? Axe Celica would be pretty cool (We don't use these where i'm from but I'll do everything in my power for Alm)) and even harder to fill colorless (infantry archer Alm?)
Could you see IS doing this? Or would the stat inflation be too much? I was thinking about Liki aaaand LMarth, both of which scale incredibly hard with the amount of investment, though with their base kits and stat lines are extremely versatile
What would you change, who would you rather see?
