>>> sys.getsizeof(int)
436
>>> sys.getsizeof(bool)
436
>>> sys.getsizeof(bool())
12
>>> sys.getsizeof(int())
12
>>>

basically even if you could you would not get any space saving ...

this may also be of interest

"sys.getsizeof(int)" returns an unreasonably large value?

As far as I know there is nothing to store booleans this efficiently in native Python, but you can checkout the bitarray library which is I think what you are looking for.
