McRae's Gunsen (interesting name :P) definitely has value in its dual AoEs, and utility mages like are proof that there are champions looking to increase both their damage and team utility at the same time. Perhaps that alone makes it important to combine both effects, but I still think a dual AoE might be a bit much for an item passive, particularly since it's also intended to modify spellcasting priorities a little. Usually item passives add to existing gameplay, rather than foster new gameplay of their own, but at the same time it's possible that these effects would just flow naturally in most combat situations. I'd still be in favor of paring down the effect into one or the other, or potentially even combining the two and have any spell launch a wave of healing and damage, but in any case there's definitely a niche for this kind of item.

If you're looking for AoE on-hit damage, I think that's already covered fairly well by, which spreads on-hit effects to two additional targets (there's no melee option, but a +  composite item might work). Periodic on-hit splash damage feels a bit situational, since autoattacker champions aren't often going to be able to catch enemies piled up in the right spot at the same moment as when they'd want to launch an attack, and the only case where this would be perfectly reliable would be wave clear, during which you wouldn't want to multiply life steal all that much. , which also has an AoE Energize effect, chains from target to target so as to be more reliable. If your intention is to emulate Guinsoo's old AoE Rage effect, then you might want to have Energize produce a state where the wielder's basic attacks would splash to nearby enemies for the next few seconds. I should've probably explained myself better, and you're right that AoE on-hit damage is a potentially interesting niche to explore, and my concern with the above Guinsoo's is the situationality of a one-time periodic AoE, not so much the AoE itself.
