What If Thor dies in Doomsday but still Thor 5 comes out after it

I mean, i think it would be awesome if both Thor and Loki died fighting Doom together, and after this, enter Valhalla but not concluding his story.

Then, Thor 5 would be called Thor Quest as it would be an introspective movie where Thor would have to find himself in the afterlife.

In the movie, thor would learn that the souls of the Valhalla abandoned this realm and so his soul would have to travel to hell to discover where these went to. Hela would return as after Thor’s death, there would be no all father to guard it. Valkirie would return to see one of her powers in the comics as the guide of the souls to the afterlife. Together Thor and Valkirie would travel through Hell, finding Jane Foster, Odin, Frigga, Heimdall and Loki (og) to release the souls from Hell and bring them back to the Valhalla. At the end, we see Thor having a great time with his family reunited but specially with his long lost brother, sending off the whole Nordic Mythology in the MCU.
