I've not heard any updates on on-going efforts to shorten AT-3032's
to make them more compact.
Unfortunately, there don't seem to be any very small profile (~6mm),
omni-directional mics that enter into the lower self-noise range of
17dB(A) or quieter. There are some moderate to high price "compact"
mics that use ~25mm capsules such as Klas Srandberg's Telinga EM-23's
[~14dB(A) self noise], Schoeps CCM-L/MK2's [11dB(A)] and MBHO's
KA200N/603A [14dB(A)]. DPA also makes a model.
There are also DIY projects underway using Primo EM-23's capsules
(the same capsules Klas uses in his mics) and some of these
schematics might be publicly available in the future. These would
require soldering skills and save some money.

I'm not sure about this claim. The Shure WL-183's spec at 22dB(A)
self-noise and field uses have borne this out. The AT 853's spec at
24 dB(A) and AT specs are known to vary pretty substantially from
field performance. They may have changed, but when I tested a pair
about 8 years ago, they did not sound like they performed to this
level. Both 21dB(A) and 24 dB(A) will sound quite noisy when compared
to your 3032's. Only side by side comparisons give one a
comprehensive sense of noise performance differences.
Also, I believe that the AT 853's have a cardioid polar pattern and
the stereo rigs you've mentioned thus far are based on mics with
omni-directional or "omni" polar patterns. That doesn't mean you
can't try cardioid mics, but the stereo imaging will be different.
