I think 104hp is going to be too small for the amount of variation you are hoping to achieve (twinkly and abrasive). To maximize space and gain a lot of different functions in 10hp with no menu diving, I HIGHLY recommend one of the Noise Engineering Versio modules. You can flash them with different firmware (super easy process) for the task at hand. I love the Desmodus (reverb/delay), Melotus (granular), and Ruina (distortion) firmwares. Melotus could cover your Clouds needs in a smaller footprint and give you access to even more functions if you choose to pursue them. This is one of the better investments I have made in euro.
Have fun and good luck!
