I do not believe it is possible in modern FreeBSDs.  The top(1) utility uses
kvm_getprocs(3), which guarantees that the ki_comm field will represent an
unaltered original command name, so no amount of tinkering with
setproctitle(3) or the contents of argv array will change that.

Accidentally, ps -c does the same.

If there is a way to do it, I will be happy to learn about it myself.
