Possible Godzilla Sequel Enemies?

So I'd like to know what you guys think of these possible enemies. Origin stories are tweaked as well for more probable reasons they could be in the sequel.

1. King Ghidora. I think everyone loves Ghidora as an enemy and he's probably the most widely known enemy of Godzilla besides Mothra (who honestly, I would hate to see in the sequel). But he probably won't be an alien if this is the case, they'd have to come up with something new.

2. Mothra. Unfortunately this is really likely, and easy to do. I don't like Mothra. i hope they use something else. Moving on.

3. Biollante. Super easy story, someone mixes Godzilla's DNA with a rosebush, but much more complicated process than what they had in the original film obviously. Or, my friend suggested that the male MUTO may not have been the obly thing absorbing radiation in Janjira, and that Biollante could be there. Who knows?

4. SpaceGodzilla. Hear me out. He was an amazing enemy, and in the sequel, he wouldn't have to be from space. He could be another member of Godzilla's genus, but maybe not same species, so they look similar, but not the same, and different powers too, like in the classic movie. And they could fight over SpcaeGodzilla moving in on what Godzilla thinks is his territory.

Those are what I think are the most likely, and conveniently, my most wanted enemies. What do you guys think? Who would you like to see?
