Yes. I'm sure you may have already found that you can't simply layer them.
You can try using "average" pattern:
normal{
average
normal_map{
[1 crackle 1]
[1 granite 1]
}
}
You can change what you use in the normal_map and even have as many items as
you like (up to POV's limit of 256).
Adjusting the numbers before the pattern name adjusts its weighting. Have a
look at the average pattern in the docs for more info.
