My Oxygen Destroyer idea for G:KotM and GvK

With the latest buzz surrounding the potential involvement of the Oxygen Destroyer in Godzilla: King of the Monsters, I thought of a compelling manner in which it can not only be used in the movie, but carry over into GvK. Here's my take:

In G:KOTM, the US government retrieves the OD that Serizawa created during the Castle Bravo experimentation against his wishes (due to his whole "humans controlling nature" narrative) after Monarch inadvertently awakens King Ghidorah from his ice prison, leading to the combined presence of 4 different monsters. They use it as a last resort against him (after initially wanting to use it on all 4 of them), taking the combined efforts of Godzilla, Mothra, Rodan and the OD to kill Ghidorah (with Mothra possibly sacrificing herself for good measure).

In a post-credits scene, we see microorganisms appearing around the decaying corpse of Ghidorah, potentially created from the combined presence of OD AND Ghidorah cells (similar to Bagan's origin which, let's be honest, he's basically a mirror image of).

In GvK, these microorganisms eventually involve into the beast known as Destoroyah and start causing destruction in the background that pits Godzilla and Kong against each other. In Act 2, Kong runs into an aggregate form of Destoroyah and defeats him with ease (mirroring his battle with the octopus kaiju in the original KKvG). An evolved Destoroyah (or vengeful surrogate, whatever) later appears and fights and kills (or fatally injures) Rodan.

Godzilla follows a trail of footsteps right by Rodan's corpse and cityside destruction eventually leading him straight to Kong. Godzilla and Kong fight in Manhattan (fitting location for a number of reasons). Godzilla wins (yes, I'm biased), but before he can finish him off, a fully-evolved Destoroyah appears and tries to finish the job for him as a form of payback. Godzilla tries fighting Destoroyah alone and gets manhandled (due to fatigue and just outright being inferior to him). Seeing what's happening, Kong realizes Godzilla's not the enemy and gets up and teams with Big G to defeat Dessy together, thus proving Serizawa's "man vs. nature" theory right.

You could also maybe throw in an arc with Kong fighting a pack of Destoroyah aggregates on SI (or some other tropic location) or Cloverfield-esque city raid with Godzilla coming to clean house on the critters (or both) for good measure, so yeah, he (or some new monster equivalent) fits the narrative better than some might think. Hence, Destoroyah being featured in GvK is actually a distinct possibility in light of this news!
