This would generally be frowned upon because you’re really combining rather than adding; this is why the actual datetime library has a combine method rather than using addition in this way.
I’m not aware of any other cases in Python where
<instance of TypeA> + <instance of TypeB>produces<instance of TypeC>. Thus, the Principle of least astonishment suggests that you should simply provide acombinemethod rather than overload addition.
