I think the initial objective of OP (independently from the "case") has some nice ideas.
I can imagine how this might actually work:
1. It should be possible to report someone for cheating (additional option when reporting. Giving proof including details would be necessary). Moderators will handle these cases in addition to other reasons like insults BUT in reduced priority because often those are not time-sensitive - so they could wait and maybe - if only a single report is there for one person, that wouldn't be handled so soon, maybe not at all until reports add up.
2. Handling cheating reports would require consultation of experts in the game as OP suggested.
3. In addition to volunteering as moderator, people could volunteer as expert in a specific game. Similar to the guru-system but voluntarily. You won't just be added, but if you reach a certain rank (top 5% percentile of players or something like that) you'd get an invitation to sign up as an expert. But it should also be possible for not-high-ranking-players to set themselves to volunteer and give a reason why they feel qualified.
4. Moderators, when they chose to handle a cheating-case, can pick an expert among the list of volunteers to discuss the case with them.
I don't know if this process is possible to add to the actual moderation-system because I don't know how it is decided now which cases they get or how the decision-process actually works and how high the workload is already. But maybe it's worth thinking about it for by now unhandled cheating-cases that are until now impossible to report as well as for possible unjust mod-decision in cases like the one presented here.
(under the assumption this one was indeed an unjust case, which I don't know but to me as someone who also played with a fixed partner only (but only a few games so far), I find it very possible because we have already been accused of cheating in chat despite we never cheated and I can very well imagine people might report us if we had played more).
In addition I want to say that I highly appreciate the work moderators are doing in general and I believe that in the majority of cases, the decisions are good and just. Also I am sure that it is impossible to get it right every time, and if someone is wrongfully accused, you should keep calm and not go full aggro about it
. So I believe in general the system is working, but I would really like to see an additional cheating-handling, that isn't being done so far. Maybe it's not realistic to handle the workload that comes with it, but it would be great if it was possible.
