There is nothing stopping someone from training and using a model that impersonates whichever historical person you want it to impersonate - except for resources and skill.

That is always the huge differentiator in the availability of tech without guardrails. Do you want a reasonably priced thing? Accept the limitations of it and the fact that it will meet safety standards (whatever those might be). Don't like the limitations? Build your own. Too hard, or too expensive? shrug wait until the price comes down, or it becomes fully commodotized.
