You can trying averaging normals.
normal{
    average
    normal_map{
        [1 bump_map1] // the number is the weight of the map
        [1 bump_map2]
    }
}
In fact, the doc says that "average was originally designed to be used in a
normal statement with a normal_map as a method of specifying more than one
normal pattern on the same surface", so this may be the most efficient way to do
it.
