I´ve just made a slippery ragdolls mod. I don´t know if they are funnier, but that´s as far as I can go at this moment.

there's jules mode ( https://modworkshop.net/mod/48477 ) but that only works on non-DLC heist and only on overkill solo mode

there's another difficulty mod on nexus that's just massively increases the spawn cap and spawnrate and it's just not a good difficulty mod compared to jules mode imo
