Shouldn't be too hard to set up a mixture of weibull distributed event times with one component having a parameter less than "exponential" (to represent the cured fraction with survival typical of an average human population) and another with a hazard like an "exponential" or worse to represent the non-cured fraction. Watch out about how the shape parameters are defined. The survival package uses different parameterization than the rweibull definitions.
