I actually said that I'm aware they have fallen out of favor. Yet they still are the biggest game a game company can make. Blizzard did not have any experience doing MMOs and they succeded (then Activision buying Blizzard screwed them), Riot gaming is also doing an MMO. And there is also Ashes of Creation in the works.
Instead of saying I have no knowledge, you could try to come with your own arguments.
Even if Divinity 4 was not designed to be an MMO. If they do hace the source code, nothing prevents them from adapting it, or even if they'd have to come up with another one, they can reuse existing assets.
And as for the funding. I'm pretty sure that if they release it following the same Early Access model. They'd get financing from the community. Also I'm willing to bet they will get a lot of money from BG3
Look, in one breath you are saying they are "not starting with zero assets" and in the next you are talking about adapting an existing system.
The fact is they WOULD start with zero assets. MMO's require a completely different resource calculation when it comes to asset creation.
If you want to understand what Blizzard went through to create their MMO I suggest you read "The WoW Diary" By John Staatz - it's sitting in my bookshelf* right now - I have read it twice.
When you say, "what if it is that easy?" you are basically telegraphing that you have not really studied the challenges that go into doing something like this. I would invite you to go do that first and then re-think what you are asking here.
*no, you can't have my book. :P
