How old is your piano? Why would it be problematic or dangerous to tune to 440?

You'll find that trying to tune a piano a full octave lower is pretty much impossible, as the strings simply won't have enough tension to vibrate properly, or keep their proper spacing, and the piano will basically sound dead. It won't even sound like a piano anymore.

Besides, there's really no need to tune that flat. If your piano is less than 100 years old, then it was likely designed to be tuned to A440. If it's over 100 years old, than it likely was meant to be tuned to at least A435 (or less likely, to A415). If the piano can't be tuned to A415 (which is essentially one note flat from A440), then the piano simply is too far gone to be salvaged at this point and you should look for another piano.

I don't think you'll have any luck tuning an octave flat; as Adam mentioned above, the strings just aren't elastic enough, so there'd be no tension in them at that pitch!

I did tune a piano to A=412hz recently owing to a section of loose pins that couldn't take any more tension. The piano was due to be replaced soon, so it was just a stop-gap measure to keep the piano playable for a few more weeks smile

At that tension, strings are likely to move around the hitch pins, or slip out of the tuning pins.
