Evolution of small things like algae and the krill which feed on it and feed the whale is quite fast. Single celled organisms reproduce on the scale of 20 minutes and hold immense amounts of genetic diversity in their populations to facilitate the success of a better adapted line almost immediately. Additionally, they are adept at horizontal gene transfer from other well-adapted organisms.
This would be great news if the whale literally only required krill to survive, but complex megafauna have complex needs, so the ability of krill and other small creatures to evolve is largely irrelevant in a discussion regarding the ability of megafauna to survive. This is especially true if you read TFA and see that the whales already adapt to eat different things as necessary.
It could easily become this fast or even faster, if we would just stop worrying so much about "playing god" and focus instead on getting good at this job. We don't have much time for this either, as AI is on the trajectory to take over that mantle in the next decade or three, whether we like it or not.
But seriously, we may not have much choice. Natural evolution stopped being able to adapt to environmental changes after it created us; genetic engineering is essentially the only way to make biology adaptable enough again.

Humpbacks have a highly specialized feeding mechanism. They only prey on krill and small fish.
The food chain really is sun -> algae -> krill (and sometimes small fish) -> humpback whale

Like what? Emotional support dolphin?
Evolution has been found to be happening 2-4 times faster than the rate earlier thought: https://news-archive.exeter.ac.uk/2022/may/articles/fuelofev...
We would need 1000x faster, so that doesn’t really change anything.
