Changing the rules of Assassin games

I am tired of losing assassin games due to somebody eliminating the wrong target, so here's a way more fair idea.
A - If someone eliminates the wrong target, that person will be eliminated from the game, and his armies become neutral. The assassin of the wrongly eliminated person will inherit the target of the person who was eliminated for eliminating the wrong person.
or
B - If someone eliminates the wrong target, he is eliminated from the game, and his armies are inherited by the person he wrongly eliminated. The person who inherits the idiot attackers armies will have the same assassin, and whoever was targeting the idiot attacker will now have to eliminate the idiot attackers original target.
In short, either option, if you eliminate the wrong target, you will instantly be eliminated yourself, preserving the game for everyone else.
