There is one, although I don't know if it is on electowiki.
Approval satisfied cardinal versions of AFB+Mono+Mutual Majority+LN-Help,
but if disapproval ballots are used rather then approval ballots,
we can create the following system:
Every voter markes any candidates of the choice as disapproved,
the sum of disapprovals for each candidate is calcualted,
every candidate is assigned a score equal to their sum of disapprovals
multiplied by negative one.
The candidate with the highest score wins.
This satisfies AFB+Mono+Mutual Majority+LN-Harm
and although it is functionally identical to approval.

I would also note that the name of disapproval voting
is also used for a disapproval version of FPTP,
and in my (limited) experience is what people will
think you are talking about.

It appears to me so far that basicly every system satisfying
Mono+LN-Help/Harm have a Mono+LN-Harm/Help equivalent,
so just like MaxMin(Support LogicalOr Equality) turned out to
be a LN-Help version of MMPO,
there should be a LN-Harm version of MinGS similar to MMPO.

Hopefully of some use
