Yup. I don't have eroff or its macros available, but the basic problem
is likely caused by the fact that one doesn't know when the .cS will be
evaluated. Try something on the lines of

.de mS
.ie '\\n(.z'' .cS \\$1 \\$2 \\$3
.el \\!.mS \\$1 \\$2 \\$3
..

and call .ms as in
.mS fig.ps 5i 3i

The macro will keep calling itself when being diverted, and will finally
call .cS when not.
