For which types do you want this return to happen?

I prefer the try-catch to be removed. Maybe it is better and more readable to do:
if..
elif
else
raise type error
Because by doing it like that you know exactly when a error is raised. now it could also be another problem being catched by the try-except construction

why return this specific dtype and not the dtype of the original obj?
this does not agree with your idea of backwards compatible i guess .
Does this work ?

again: Why convert to this specific dtype?
Maybe it would be better to use the original dtype?
