I'd just be happy to see Wildfire trigger Hypercharge on activation.
AFAIK, we never use Wildfire without also triggering Hypercharge.
So it's just kind an awkward triple oGCD cast whenever it's Wildfire time.

On the topic of Hypercharges effect, why not have it change Split, Slug, Clean and Scattergun into Hypercharged versions you use once each with the 1.5s GCD and additional effects, then finish with Heat Blast resetting the Gauss/Rico cooldowns entirely.
