This seems like a cool idea, just not for Geomancer. We know a lot about the lore of Geomancy in Yanxia and nothing about them says healer. Like they were dropping Garlean airships out of the sky.

I do think it'd be cool to have a real musical class especially a healer, this feels more like what Bard should have been instead of dollar store Ranger we got now.

Plus we know they're not gonna do anymore split jobs since they're very near to nuking classes as a whole.
