Just a couple ideas to try or disregard as you see fit.

If you will accept increasing the vertical separation of the two mics
then you could put a ball head on each mic.  The home made equivalent
would be built from the plastic mesh eggs that Walt linked to earlier
from a craft source on-line.  In long distance outside recording the
phase problems from increasing the verticle axis distance in XY is not
so great as in close indoor recording.  Outside you are usually
recording sounds on a narrow horizontal plane.

If maintaining the vertical alignment is important to you, then you
want to go to a bigger windshield and place both mics into a single
windscreen.  I would buy the Shopvac filter element and leave the
bottom cap in place to mount your tripod, stand or handle to.  I would
cut two access holes in the side about 2" diameter.  This would
involve a wire cutter and a filet knife.  I would stuff those holes
with 3" thick foam rubber cut into 3" rounds.  With the foam placed on
a table I would cut the mic holes in the foam by twisting a sharpened
copper pipe through the foam.  The foam will now serve as your shock
mounts and mic support structures.=20

Now stretch a stocking cap or extra large women's knee high over the
filter element and cut the holes in it where the mics will pass
through.  If you used a nylon material stocking hat melt the cut edges
with a flame to prevent unraveling.

Rounding the top will add a very small amount of additional noise
reduction so can be considered optional. I would use a plastic food
strainer for that with the handle cut off. Placement of foam over the
bottom plate will reduce the resonant bump that you may or may not
notice from sound bouncing off that hard bottom plate.

PS Pardon my attitude lately.  To say that I have MN winter cabin
fever would be an understatement.  Get me out of this house I am stuck in.
