You still aren't telling us what it would _mean_ for the sticky bit to
"work on a group", but I have a guess.  Normally only the user owner
of a sticky directory is allowed to delete other people's files from
it, but you want to grant this special power to a group.  There is no
way to do that on a standard Linux filesystem, not even with ACLs,
though I suppose a custom filesystem (e.g., a FUSE) could support it.
It's probably easier to give members of the group a way to run delete
commands with the privileges of the user owner of the directory.  I
can think of a few ways to do this: a sudo power, a restricted SSH
authorized key, or userv.
