What are your ideas for a Zelda game with a complete map?

If you were to make a mega map for a BoTW3 game that included every canon land (Hyrule, Termina, Koholint Island, Holodrum, Labrynna, Twilight, Skyloft, etc.) traversable, how would you arrange the map?

Where would the player start?

How would the player travel to the different areas?

What adventure would cause Link to need to travel across the entire world? And all its parallel worlds?
