They've surely started working on it already. Current "AI" (LLMs) aren't perfect. They require constant human adjustments.
I'm an auditor for a "machine learning" algorithm's work, and it develops new incorrect processes faster than it corrects them. This is because corrections require intervention, which involves a whole chain of humans, whereas learning new mistakes can happen seemingly spontaneously. The premise of machine learning is that it changes over time, but it has no idea which changes were good until it gets feedback.
So, to answer your question, I'm sure they're throwing a ton of money at that. But when will it be viable, if ever?
Finding actors for Link and Zelda, fine. But who on Earth could do Ganondorf justice? How do you translate the Gerudo to live-action film? Black actors with red wigs? Mixed-race actors with red wigs? Mixed-race actors with their natural hair, straightened and dyed red?
There are some lighter-skinned Gerudo in BotW/TotK. Would the actors all be pretty monotonous in look to give them a coherent race identity?
If that were a thing, the right would clamor that it should also apply to judges appointed by the defendant's political opponents, and that would get all the cases against Turnip Dump tossed
You are either misunderstanding what is actually important, or being obtuse in a plea for attention.
