I have found it practically impossible to make a decent sounding 32' stop from 16' samples. It just never sounds right.

It can be done. It was done on the St. Georges Casavant, and Ken Bales did a credible job on it. He extended the Swell 16' Fagotto done into the 32' octave to use on the Pedal. He also extended some of the other ranks done an octave (all of those were 4' or above), and in each case the results were good.
It is possible to do this in Cool Edit, and probably in other audio editors. In Cool Edit, it is done without extending the examples, so the attack and release examples are not stretched out. I have done it that way and with Pipe Tune, and usually go with Pipe Tune myself. Instead of taking the 16' Octave and transposing the whole 12 notes down, I take the last two, C and C#, and use them, first going down one whole step for A# and B, then two whole steps for G# and A, etc.
In order for that process to work, both the C and C# have to be good notes. If you develope six notes from a bad one, you end up with seven bad notes.
