Is that even "possible"? As in, they have to follow the rules of the organization, which have some criteria laid out. Not sure who could stop them from changing, though. Like, I think the original intent was to have done the most the preceding year, but now it's more of a lifetime award. So perhaps they can change or add different categories if wanted.
That's the only reason I can think of for this - like, Alfred Nobel or some other dead donor set rules that they aren't allowed to change now. But I haven't seen anyone confirm it.
In 1968, the Nobel Foundation accepted a donation from the Swedish central bank to establish a prize in economy, but in hindsight that was a pretty bad idea, and the probability of them accepting future donations to establish prizes in other fields is very slim.
