Go right on ahead.  You could implement it like this:

class superenhancedlist(list):
    def isempty(self):
        return not self

>>> a = superenhancedlist()
>>> a.isempty()
True
>>> a.append(1)
>>> a.isempty()
False

Amazingly useful!  Go ahead and use that in all your code.  Anyone
else who comes along and looks at it or tries to maintain it will
really love you for it.
