Great stuff Tom ! :D
I like how the Mules have enough weight in the mids, to make the ascending string bends really sing in a way redolent of ( Brian Robertson era ) Thin Lizzy ; yet still have enough 'bite' when required. I suspect that the Riff Raffs would have been less adaptable between the two soloing 'voices' that you use, even though they are an awsome pickup in their own right. As you said, that would be fun to play or hear live ! :)
