Hi Lou--
This is a question the micbuilders list is surely capable of
addressing. There's Dave Latchaw DIY fig 8 circuit made with ECM's:
http://www.mp3forkidz.com/mic/blum.html. The lower noise Primo
EM-23's or EM-158's might be similarly configured into a DIY fig 8.
As Walt pointed out, the MKH30 circuit uses a fairly elaborate
push-pull capsule design and many, if not all fig 8 mic circuits seem
to require some low Hz boosting to more closely match the low-end
response of gradient cardioids. For a less complicated solution, the
multi-pattern Rode NT2000 could be workable for some applications
(though very heavy and not yet humidity-tested as best as I know). It
has better bottom end response over the lower cost NT2-A and
NT1-A's. Rob D.
