VENOM/CARNAGE spawning in INFINITY WAR?

Let's put aside the idea of 2018's Venom solo movie tying into the MCU, because I doubt it. However, the MCU could have their own Venom, or at the very least Carnage.
I understand that Comic Fans want accuracy and you can't have Carnage without Venom, but hasn't the MCU already changed up the classic myths for many things?

In fact, it has already been stated that the classic origin story for Captain Marvel will be completely altered to fit into the MCU universe. Civil War was also it's own complete thing compared to the original comic version.

So think about it, Infinity War is going to space, the Guardians of the Galaxy are even involved, not to mention Doctor Strange. Finally we're leaving New York, and from the sound of Phase 4, it might for the most part be for good.

In the original origin story of Spider-man's black suit, Peter Parker obtained it during The Secret Wars, IN SPACE.

Pretty much a mega Avenger type mega super-hero role call blockbuster of a story-line. So, during an adventure in space with-in part one or two of the Infinity War films, why not have Peter Parker pick up the alien suit?

Goose bumps of a epic idea, eh?

Also, since Sony will be pushing their own Venom, and if MCU may be granted forgiveness from fans. Why don't we just skip to the most exciting symbiote that hasn't had a movie appearance yet? I mean we could still have the black life form appear to be a lesser hostile threat, but instead of making Venom, it split into Carnage early. Or better, Peter Parker could represent himself in a extremely unprecedented red symbiote suit.

I think fans could forgive Marvel Studios if somehow Peter Parker brought forth Carnage in a very unpredictable and exciting way.
With that said, do we need two Venoms? Can we not only give Peter the suit during Infinity War, but also summon forth a extremely charismatic villain?

Sadly that's kind of a weakness of Marvel, they are really bad at producing interesting villains which seems ridiculous. Given that, Carnage would represent a complete shock to the movie goer's system - only problem is while still producing the suspense - the film will still have to be PG-13.
