PoE Stormblind, Projectile builds

Heya folks, So, since I saw Wilma's Requital, I couldn't help but think it seemed like it could be a blast for a Wand Ballista build with Alt Kinetic Bolt. However, the best I could figure for the build would be to more or less rip off Mathil's build from Kalandra league. I would appreciate any assistance folks could offer in regards to refining the build concept.
