Are we finally getting our Shadow Isles AD Carry? (New Thresh Lore Section)

Thresh Thresh is a sadistic, spectral reaper who relishes tormenting the living and the dead. Once a jailer who mercilessly brutalized all under his charge, Thresh was hanged from his own chains by the prisoners he had tortured. With his vicious essence unbound, the Chain Warden roams Runeterra in search of prey. He derives twisted joy from slowly breaking the minds of his most defiant victims, before trapping their souls within the sickly green light of his lantern.

This will probably never happen (knowing the way Riot is with presenting themselves perfect opportunities to create champions cleverly linked to current ones yet being completely oblivious to them), but it could be possible that a twisted iteration of Senna could be released unto Runeterra. I can just imagine her in-game against Lucian with a VO quote along the lines of "I... I know you Lucian. Or knew you... Did I?" Or something like that.
