As you may already be aware the team formerly known as the Icconics, (Billie Kay & Peyton Royce) retired a few weeks ago after a spell in TNA. 

They were certainly not Becky/Charlotte level workers but they were solid workers, an actual women's tag team and great heat getters. I know Meltzer hated them particularly Peyton, but what did you think of them?

Also given what they bring to the table, why would a)WWE release them & b) AEW not immediately pick them up? 

I didn't notice them when they were around and I didn't notice when they were gone.  That's probably why no one's in a rush to pick them up.
