This is a very interesting chain of thought, Natasa.
Paul Darrow mentions in an interview that he was told by the writers, 'We think now that Blake's gone you ought to be a little more moral', which he obviously refused.
LOL
B7 obviously toys with the 'uncertainty principle', probably not because of any conscious interaction with deconstructionism, but simply because they both reflect our age.
I sometimes wonder to what extent the formal convolutions of B7, the kind of thing you mention in this post, were thought through at all, by anyone. It's not just reflecting the age, I don't think, because you wouldn't find it in any other show of the time. But I'm not suggesting anybody put it there on purpose either.
