It pains me to say this, but the laziest and possibly most effective way to address conjures is to simply get rid of them. By that I mean get rid of the weapon bundles. Take the most iconic, or most useful skill from each kit and turn that into conjure weapon utility. Keep the animations so it looks like you're still using the weapon. Like keep Explosive Lava Axe, Frost Storm or Deep Freeze, Lightning Leap, Stone Sheath, and Fiery Whirl. Call those the Conjured weapons. Give them modest cooldowns and/or charges. Call it a day. It might slightly step on Arcane skills territory (looking Blast and Wave), but It would take the most useful of the Conjure skills and make them simple on demand utilities.
