While it is possible to "fake out" a shell script in this manner,
it isn't likely to help you much.  In V7, for example, shell
scripts do not run setuid, and anything you faked the script into
doing, you could have done yourself anyway.  On systems such as
4.1bsd, which do allow setuid shell scripts, the script should
re-set all inherited parameters itself anyway.
