Maybe I missed something in your question, but what we have in France seems pretty close.
Our ballots go into a transparent urn, you need to be registered in a voting office and show an ID paper to vote, and people counting the votes are typically a mix of local state employees and volunteers citizens (and given that most people don't want to spend their Sunday evening counting ballots, it's quite easy to get a place).
Now I guess it moves the trust onto the ID system and the aggregation of local counts into national results.
Same exact process in Italy, except we also use ballot tagging to fight organized crime. For all the problems we have, trusting the results of an election isn't one...
