'synthetic' Ge transistor?

.....when repairing or cloning old fuzz units one often needs
germanium pnp transistors, sometimes with a gain of 200 or so.
These have pretty well dried up, and the germanium specialists
are pretty pricey....so i wondered if anyone could think of a way 
to make a 3 terminal drop in equiv. from current parts? the 
crucial thing is the softer knee of the characteristic curve.

Of course, if anyone has an idea for a ckt that allows a 
synthetic transistor to be made with selectable characteristics
this would be a boon to all those struggling to replace oddball
ones in lightning struck bits of vintage gear.....

hopefully,
