The source to su is available. Linux has a compiler and the tools to
overwrite the system version of su with a custom version (assuming you
have such privileges) or use other methods to accomplish this sort of

But, since I assume you really don't want to just add repeats of the
same hoop, I can suggest you look at sudo and /etc/sudoers instead.
