Sure, Chris, post some pics and sound files from your COS11 rig: "nature" "sound"

Some recordists feel an accurate head-like shape/surface is crucial.
At one time I believe Gordon Hempton was using a Neumann KU 81 and
experimenting with clay and creating different ear shapes to improve
the stereo imaging. Gordon would be first to tell you that the 81 and
100 aren't the quietest mic capsules. As for mic size restriction,
I've seen what looks like a properly scaled/shaped head with mounted
mkh-20's, which are on the scale of at-3032's.

There are also many simplified head designs such as Rich Peet's
"blockhead" that
will easily accommodate larger omni mics like the AT3032's and
mkh20's. The SASS, and other head-spaced rigs employ many of the same
principles.  In addition to oft-cited "tree trunk" rig,  I've heard
very good stereo imaging with $2 foam wig holders.

A lot depends on the sound levels/locations. For ambience in quiet
places I'd be inclined to start with quiet omni mics and solve the
"head" problem 2nd. For loud places on a budget, Panasonic WM-61A
capsules can be carefully matched and are quite flat in Hz response.
All condenser mics will act-up in moist conditions at some time.
WM-61A's are so inexpensive that making several back-up pair is
doable. There are several "head" specialists on this list. We'll see
what we can learn from your pics and sounds. Rob D.
