I wouldn't be TOO hopeful here.  Tech pan is such a high contrast film
that you need developers specifically designed to produce low contrast
results.

It may be possible to try something like water bath development which
is normally used to produce low contrast negs.  See Ansel Adams "The
Negative" for a description.  I suspect it would be easier and more
predictable to just go with one of the conventional developers for
tech pan.

Kodak's pushing their liquid technidol, which I'm about to try soon,
but it's awfully expensive.
