I would look at writing a small shell script in ~ldm/util and calling that 
with the pipe action:

EXP     ^(........\...)d\.Z$
        PIPE            -close
        util/process.sh

The create the shell script process.sh:
#---------CUT---------------------------------------
#!/bin/sh

target=/tmp/file.1

cat |uncompress |crx2rnx - > $target
#
#---------CUT---------------------------------------

I've gotten this to work with some of the gempak decoders in a similar  
manner.
