Hotaru is still one of my top 10 favorites. If Havik is in the comic, I still have hope for Hotaru to return somehow.
My main wish for the MK11 story is for Edenia, Orderrealm and Chaosrealm to finally be involved. Frankly, I'm tired of the focus on Earthrealm, Outworld and Netherrealm. I think it's time to give the others a chance. There's no greater opportunity than Dark Empress Kitana trying to reclaim her home by taking it from Kotal and trying to merge it with the Netherrealm. Havik can get the ball rolling, while Hotaru is called in by Raiden to help maintain balance among the realms. Do it, NRS.
Some things I believe will happen, because too many endings share the premise:
1) Liu Kang, as the new overlord of hell, sets his eyes on Earthrealm, potentially to specifically oust Raiden.
2) Shang Tsung returns. He's too iconic to forget about for 8+ years, and with Quan Chi and Shinnok out of the picture, MK needs a sorcerer on the roster.
Edenia, yes. But God, let's leave Chaosrealm and Orderrealm in the old timeline. What a bunch of needless distraction that was. It never felt like it fit.
Well, Havik is canon, so there is indeed a Chaosrealm.
The only problem about them is the lack of time for them. They have their role on the universe, but have never gotten their fair share of focus.
