Banner of Command + Azir?

This was actually suggested to me by CrazyMLC, but I thought I'd bring it to the forum as its own post to see what people think about it.

Currently from what I know, Banner of Command does not work with Azir. His little dudes are spells, not minions. This is probably intentional to some degree. It's definitely possible that it would be too much trouble to put in. However...

Banner of Command is currently not built, or at most very very rarely and most often when picked it is a troll pick.

For anyone too lazy to look up Banner of Command because no one ever sees it so no one remembers its stats, here they are. +80 ability power +20% cooldown reduction UNIQUE – VALOR: Nearby allied minions have 15% increased attack damage and ability power. UNIQUE – PROMOTE: Transforms a nearby siege minion to a more powerful unit. You gain all the gold this unit earns. 180 second cooldown.

The stats aren't that amazing in general but with Azir it might be interesting. 20% cooldown reduction? With a Nashor's, he has it maxed, and very quickly as those items are not the most expensive out there. 80 AP isn't that bad either. But what's interesting is the aura, if it had any effect on his soldiers it has the potential to actually be kind of cool. Not to mention it's really nice with his lore. He's an emperor! He commands armies- and with that he'd not only be buffing his natural soldiers but would also buff his minions so it feels more like he's a true emperor.

I might actually build it on him just for fun, even if it doesn't work on his soldiers. He would be pushing on turrets pretty hard, would take down the turret, and be able to place his own.

But I was wondering, does anyone else want to see this? A sort of change to what everyone currently builds? Seeing something new? At the same time, I'm not sure if it would make his soldiers crazy or not. I'd probably have to see it tested before I can really decide how much of an impact 15% is on his damages.
