The WHFB Hellcannon could fit in as a Cannon of Khorne.
The old Daemon Engines of Khorne from Epic were all close combat focused and all had short to medium range at most weaponry, with a focus on more shots, and were usually of autocannon or so strength, with a few shots of approximately battle cannon in strength. The Cannon of Khorne was the outlier having range and AOE, but randomness and posing a significant risk of blowing itself up.
Khorne is about overcoming the foe through one's own strength and abilities. At its most basic this reduces down to close combat, but the short range weapons also fit that philosophy because it puts the wielder at risk. Khorne dislikes "push button" warfare and precision long range firepower, as the wielder is safe and removed from the visceral nature of combat.
