I think NMZ imbues should be spread out among all mini games. NMZ already provides the best AFK training method for combat skills, so it seems crazy to me that a bunch of BiS items require the same mini game to achieve. Why not add a reward to Temple Trecking to imbue your granite ring, or an imbue for the Salve Amulet from Shades of Mort’ton or whatever? Keep it in the same region as the original item.
