I was thinking more of an ult that would force Shard to channel and remain immobile while only absorbing attacks from a certain direction, which would have different gameplay and purposes than (it would also synergize a lot more with Shard's kit), but that is by no means the only option out there.

One of the many issues with confusing gameplay is that it tends to muddy counterplay as well: the clearer a gameplay mechanic, the clearer the counterplay behind it, assuming it has counterplay. By contrast, you could add a ton of counterplay to a mechanic that's difficult to recognize, and people will have a hard time figuring out what to do. In this case, there's also not that much counterplay besides AoE, which is a recurring problem among in-combat clones, since attacking a primary target bleeds into attacking their clone, due to the damage transfer. Basically, this is a prolonged damage steroid for your marksman that also makes them tankier, which doesn't lend itself to that much in-depth interaction. It also doesn't really synergize with any portion of Shard's kit, and you'd be better off finding some way to divert damage away from your team without just straight-up buffing your ADC.
