I'd like to have something similar: Let every dice roll half the maximum result (D20 always rolls 10, D12 always rolls 6 and so on), both for the player and enemies in all aspects of the game. And maybe add an easy mode tied to the Explorer difficulty that gives the player an advantage and the enemy a disadvantage, like instead of 10 for players and 10 for enemies with a D20 it's 12 for players and 8 for enemies. This would still be fair and make save-scumming obsolete. Either you have the character stats for a certain check, or you don't. It would also eliminate (bad) luck and make everything more predictable. I guess in terms of configuration it would be best if users of the mod could simply adjust the min-max range of both friendly and unfriendly rolls for each dice type.
