PATH is just a regular variable like any other.  If you want to remove
something from it, use whatever text processing tool you like.  The
shell lets you set environment variables only for the command being
executed using the syntax "var=value command arg ...", so:

PATH=$(perl -e 'print join(":", grep(!m@^/(usr/)?bin@, 
       split(":", $ENV{PATH})))') cmd.exe /k batch-script.bat params
