I'm currently level 67 and Survival difficulty is starting to become a little bit too easy. I believe that on Survival the difficulty multiplier is set to 2x meaning you take twice damage and deal half damage. Is it possible to increase the multiplier perhaps by console commands or by editing a config file somewhere?

There's no known way to achieve this in game, but there is a mod to help you out. It allows you to fully modify all dealt and received damage.
