Next Patron Appreciation Artwork (Patreon)

So I'm pre-planning something, like the Aetra Artwork I did, but there's gonna be 3 characters this time :) Here's my vision:
2 Characters (Most likely female) are doing it on a Hospital bed, in Nurse outfits of course ;) and the 3rd character (Also in a Nurse outfit) is looking back towards the viewer, with a Clip Board listing names :D I'll prepare a WIP sketch of what I'm talking about sometime :U

My Question to youse is: Who should be the Characters? ;)
