Actually everyone understands already. Things have been said like 'which is still a crazy amount of work'.
NO one is failing to understand, well except you in your keenness to assume everyone but yourself is too stupid to grasp basic concepts like how long it takes to make new characters.
Everyone understands how damned much work it would be, you might have noticed but nobody is volunteering to actually do it, just vaguely hoping it might be done. No one is even really asking it be done, much less that you do it personally, just saying it'd be cool if it was and exploring the idea of how it might be.
Pretty much everyone post in this thread has also alluded to how much effort this would take, often volunteering new problems that would prevent it too, even with imagining corners that might be cut to lessen it, another clue that everyone in this thread understands what they're talking about.
