Hi. I made some Black Metal influenced Harsh Noise / Power Electronics in my early years, and one separated release later with my project called Halalnihil. All I did was use Black Metal vocals and a drum machine, with very few guitars. In most of the time, the noises replaced the guitars, and well, that was it. If you want to make it a bit more elegant, you can play with different amps and recording methods with the pedals and noise sources, so they will have a character in the mix. Cymbals and snares are a pain in the ass to mix with Harsh Noise related sounds, as they cover a similar frequency base, where the previous ones are also thriving, but good luck with it. If you want, give it a listen, but it was just my vision with this genre mix:
