And how many racial powers out there really leave you worse off? Halfling's second chance has about a 1/20 chance when the monster could critical when it didn't before. Elven accuracy likewise has a 1/20 chance and that's only if your DM uses crit-fail rules (assuming you only use those last two when you were hit or missed, respectively).But you have a 55% chance of making yourself better.
Just be sure it works both ways for players and enemies. I don't think it's an unbalanced house rule to allow "bonus saves can't make you worse." Even lets PCs potentially make bonus death saving throws, although short of a wad of modifiers, a 1/20 chance of a good result isn't overwhelming.
