I Know It's A Bit Far Fetched, But What If "The Wonderful World Of Mickey Mouse" Actually Takes Place

I know it's a bit far fetched, but what if "The Wonderful World of Mickey Mouse" actually takes place in the Land of Forgotten Tunes?

[It's just a theory (A game/film theory) but have fun reading]

Okay, so in the Disney Games "Epic Mickey" and "Epic Mickey 2: The Power of Two", we see quite a few characters that aren't supposed to be in the normal world. Oswald the Lucky Rabbit, Clara-bell Cow, Horace Horse Collar, and a few others can be seen walking the streets of "TWWOMM" but they make their own more memorable appearances in the Land of Forgetten Tunes as characters who were replaced and forgotten (no longer having hearts of their own). Oswald specifically was the original Mickey Mouse who's idea was stolen by one of Walt Disney's co-workers, but fortunately for Mr. Disney, he came up with the concept for our lovable Mouse and Oswald was quickly forgotten. He is a partial antagonist/protagonist in "Epic Mickey 1" and then is featured as a playable main character in "Epic Mickey 2". Recently, he showed up a few times in "TWWOMM" as a random cameo to some of Mickey Mouse's adventures.

The main issue is that Oswald, due to not having a heart, is unable to join his "brother", Mickey, in the real world. This means that Oswald never left his home with the other forgotten tunes, but if that's the case, then how is he joining Mickey and his friends out in the real world? It's impossible... unless Mickey and his friends are in the Land of Forgotten Tunes with him. My (and my brother's) theory is that "The Wonderful World of Mickey Mouse" takes place years in Disney's future when Mickey Mouse and his friends get boring to their audience and are replaced by new characters. They are forgotten, landing them in their new home along side the other old tunes. This way, they can play together forever along side the characters of Disney's past.
