I don't know why you'd want to reverse it, even if you could. When
mounted properly, the nodal point is closer to the subject than the
film plane, which is how it is designed. You reverse a non-macro lens
because it is designed for the opposite case!

I'm not sure how you can say this. There's no general way to tell
that "lens X will have a field width of Y when mounted backwards."
That all depends on the design of a particular lens.
The Zuiko 20/2 macro is very specialized for a reproduction ratio
range of (I believe) 8:1 to 16:1. Reversing it isn't going to improve
on that!
