你这个想法很好,不过没有普适性!抄一段爱因斯坦的想法如下:
Einstein noted that, if the kinetic-molecular theory of heat is correct, the laws of thermodynamics cannot be universally valid, since fluctuations must give rise to microscopic but visible violations of the second law when one considers particles sufficiently large for their motion to be observable in a microscope if suspended in a liquid.

爱因斯坦好像还表达过类似的,如果想说某个理论是错的,只需给出一个反例就够了。
据我所知,目前还没有一个可证实的反例来推翻热力学第二定律。
另一方面,要证明一个理论是普遍适性的,笨办法就是遍历所有条件,看似道理很简单,但是无法实现的。寻找和构造特殊的例子是个好办法,但得符合客观实际,并有可检验性和重复性。
