I'll answer nonetheless.

This is already done. -listcoef- has a -matrix- option. If 
specified, the results are returned in r() as matrices. 
Example:

. sysuse auto, clear
(1978 Automobile Data)

. qui logit foreign price weight

. listcoef, matrix

logit (N=74): Factor Change in Odds 

  Odds of: Foreign vs Domestic

----------------------------------------------------------------------
     foreign |      b         z     P>|z|    e^b    e^bStdX      SDofX
-------------+--------------------------------------------------------
       price |   0.00093    3.100   0.002   1.0009  15.5156  2949.4959
      weight |  -0.00588   -3.461   0.001   0.9941   0.0104   777.1936

. return list

scalars:
            r(pvalue) =  1

macros:
               r(cmd) : "logit"

matrices:
           r(b_facts) :  1 x 2
            r(b_fact) :  1 x 2
             r(b_sdx) :  1 x 2
               r(b_z) :  1 x 2
               r(b_p) :  1 x 2
                 r(b) :  1 x 2

. matrix list r(b_sdx)

r(b_sdx)[1,2]
           price     weight
SDofX  2949.4959  777.19357

. matrix list r(b_facts)

r(b_facts)[1,2]
             price     weight
e^bStdX   15.51555  .01037077
