No, it wouldn't, because it doesn't show an exclusive one way relationship. For instance, what determines the desire to conduct the test that shows this relationship? If it's just chemicals, what makes it valid? It obliterates its own meaning in the performance of the experiment.
That is, driving the internal state from an elegant external set of tools disregards the drive to conduct the test or the tools that do this. From whence do they come? And if it's just 'frisky dust', it obliterates the drive to determine the truth as some sort of higher organizing principle, as it too is but 'frisky dust'. Did you decide to do the test or did the chemicals, in some way that science cannot determine and probably never will, decide to do the test? If 'frisky dust' decided to do the test, then there was no decision and all 'proof' is rendered meaningless.
And all of this falls prey to the myth of the given, the myth that the perceptions and their extensions simply describe a pre-existing world with increasingly exact detail.
