Not sure it's a good idea.
For 2p it's ok.
But in games with many players, especially Hanabi, Saboteur, it causes problems.
I think that instead of making red thumbs more powerfull maybe a good idea to make more powerfull green thumbs. I think that green thumbs should be for good people with whom we want to play, for others we need a yellow thumb that means "OK player". Now we give green thumbs to all players who didn't disappointed us too much. I'm not sure we use thumbs in the right way.
Another idea is to make thumbs connected with specific game. For the case you just don't want to see a player in some games.
