I Just Immediately Thought If A We Bare Bears What-if Y'all If There Was Another Movie

I just immediately thought if a We Bare Bears what-if y'all if there was another movie

What if there was a We Bare Bears movie, but it was an entire flashback movie of the bears as cubs before they met, where it would show when they were born, them with their moms and how they got orphaned, and the movie would end in these ways

1. The movie ends with the 3 meeting up

2. Them as adults (like in canon) and the 3 would look at the sunset together, being glad they're all brothers

3. (And probably the saddest) The are now older (around their 40s) where the bears now have their own families (like a wife and children, they would be bears too btw) and the 3 reunite (probably cause 2 would move out of the cave, probably Panda and Ice Bear) and THEN another time skip would happen when they're elders, AND THEN another time skip would return and Panda and Ice Bear die from old age (we'd also see how they die) and then it shows Old Grizz in his 70s or 80s paying his respects on his brothers' graves and then says "Bros for Life" and it would probably cut to Grizz dying as well, meeting his brothers up in heaven (it would also end how the movie ended)

4. (Also probably the saddest) It turns out it was all cub Grizz's imagination, and he is on the streets crying like how he did when he was stuck in the tree (This is a joke. If it did end like that I would be very pissed)

Anyways what do you guys think?
