to use on both whm & sch, mostly because many scholar skills are so very similar in color and I wanted to more quickly discern.

When I'm on whitemage, this macro behaves correctly and shows Esuna's picture on the hotbar. However, once I change to scholar and try to use the very same macro, the macro picture is changed to the default grey "M" on the hotbar.
You can at least assign it the Esuna icon rather than the grey "M" icon in the macro editing window. That doesn't give you the cooldown display like the /micon command can, but if it's the global cooldown, then you've likely got that showing on most of your hotbar slots anyway.

I don't think you're going to be able to get an Esuna icon showing its cooldown when Esuna itself isn't on cooldown, Leeches is.
