1. Most stereo mikes don't allow one to move the capsules so that they are
back-to-back. Also, that would only approximate a figure-of-eight pattern
because most stereo mikes are cardioid pattern.
2. Well, if you knew how, you could. But you wouldn't need a stereo mike
to
do that. If you could figure out a way to change patterns on a cardioid
mike,
you could change the single diaphragm to figure-of-eight.
Why don't you just buy an inexpensive stereo mike and use it?
