Theoretically, yeah. 25 years sounds like it should be long enough for Onaga's return, if not him coming back sooner due to Shao Kahn's supposed complete destruction at the end of MK9. Thus, possibly no one to usurp his rule of Outworld again.

Now, depending on how it's executed, I certainly wouldn't mind the One Being making its first official debut, whom was also said to work through Shao Kahn, not just Onaga. That would explain Kahn's obsession with always wanting to merge other realms with his own (Outworld), because the One Being is only dormant with the different realms being separate, but when more realms are merged together, that just makes it one step closer for his return, in addition to Onaga putting the Kamidogu together and all that. So both emperors of Outworld could've become puppets or vessels for the One Being to work his will all along.

Also, not a fan of him but Blaze himself became corrupted by Onaga's holymen during his years of capture. Could that possibly be something that happened during the new timeline too, or... ? Curiously, you don't even see Blaze in any of the Pit stage backgrounds in MK9 like you did in MK2 along with Hornbuckle, so who knows.
