Are you looking to piss off your home game players? This is a typical failing of home games, don't go so far off of your rocker about it.

"...I know there is a rule in place somewhere, where any player can request to see a player's mucked hand. "
The typical casino cardroom rule is, anyone at the table can ask to see a hand that was mucked during the showdown, assuming that the hand called the final bets.
However, this rule is primarily intended to curb collusion, not to use in order to irritate someone or take revenge against them because YOU are irritated. Seeing their cards rarely gives you valuable information and usually backfires.
Players are allowed to muck their cards if they choose to, but you could insist on seeing the mucked hand. I would advise strongly that you DON'T ask to see the hands, unless you suspect something fishy going on between two or more players.
You won't gain as much as you lose by forcing this issue IMHO.
