If we developed powerful enough telescopes, would we be able to witness the big bang itself?

We can see the CMB (cosmic microwave background), which dates back to the time where the Universe was so hot that the gas in it was ionized, i.e. it was opaque to light. This was around 400,000 years after the Big Bang and it's as far as we can see back. If we could see neutrinos just as well as photons, we could simply whip out our neutrino detectors and see the cosmic neutrino background, which was emitted a few minutes after the big bang IIRC. But since neutrinos are so hard to detect, and because the sun is emitting a lot of them, this won't be feasible in the foreseeable future, if at all.
