The only commonality they share is that they both exist on the Internet and they stream. Their business models are completely different.
Except, with very only a couple of exceptions (baby Yoda),the integration with segments such as merchandise, leisure travel, etc. have not succeeded. This may change over time, but the need to book a trip to WDW and experience GOTG at Epcot because someone saw the last movie is not a reality.
You sound like a someone making a sales pitch. The problem for your position is that none of what you're describing has happened. D+ Subscriptions are flat, merchandise sales for the latest Pixar, Disney Animation, MCU, and Star Wars releases are non-existent or flopped. The failure is compounded by the fact that everything coming out of Disney has a $200M+ price tag on it.
Using The Marvels, add another $150M for marketing and you need this film to bring in $800M gross at the Box office to break even. It won't even make a 1/4 of that at the Box office, how can you reasonably expect merch, Streaming, or whatever to make up that difference? We can do the same for Indy 5, that film needed to make $1B just to break even. Elemental needed $750M, Lighyear needed $600M, Antman needed $750M. All tentpole franchises that under no circumstances could deliver the necessary return even if every possible piece of segment integration was firing perfectly.
Want to do DTC original content? Ms. Marvel, She Hulk, Andor, Secret Invasion, Ashoka, and Loki all had budgets well over $200M, do you think Disney got the return on that they were expecting considering they were amongst the lowest rated D+ originals ever?
On paper it sounds like a surefire winner. In reality it has been a failure because the level of segment integration is a pipe dream. Disney certainly has not helped this by completely bungling so much in their different divisions which "should" have been capitalizing on this, but are not capable of or don't know how to do it.
