I've certainly considered doing that myself, but haven't gone any further. For a double unit, you'd need two 1ohm resistors, preferably rated 50watts minimum. Whether that would prevent resistor 'exploding' through water penetration or whatever the cause, is debatable. The main problem is fitting two resistors onto the fan guard. You'd have to organise a second mounting point which might be easier said than done. Of course anything's possible with enough effort. Realistically, the chance of anyone's fan exploding is pretty small, around (0.3%) according to Jules who's supplied more than anyone. My view is try to minimise the damage IF it happens.
So far I've simply changed the 80amp fuse to a 40amp to reduce the possibility of frying the harness if the motor is seized or something stops the fan from turning.
