Okay, so, whenever a tornado forms, it has a certain chance of becoming a rainwrapped a tornado. This chance can either be a percent, or an odds to 1 setting in the config, to change how often rainwrapped storms occur. Anyways, what could happen, is if a tornado becomes rainwrapped, the rate of rainfall with the storm will double. For example, if you had Precipitation_Particle_effect_rate set to 1.0, with a rainwrapped tornado, the rainfall in that storm would be equal to if you had that setting set to 2.0. You could also maybe do Low Precipitation storms and maybe even High Precipitation storms with a system like this, where High Precipitation storms would have the rain rate doubled, like in my rainwrapped tornado idea, where a Low Precipitation storm would have a rainfall rate of half, so if Precipitation_Particle_effect_rate was set to 1.0, in a Low Precipitation storm an equal amount of rainfall would fall as if this setting was set to 0.5. The amount of rainfall change could be customized the config, and so would the chances of a tornado being rainwrapped, LP, or HP. Anyways, I hope you like my idea!
