EDIT: I wrote all this up just to reread and see that Nurses were more or less how I imagined in OP already. Do not post before morning coffee.
Original post is in the spoiler tag, but TL;DR Nurses should be able to do A, B, and C, and they sorta pretty much can. Unlike as proposed, I think Nurses should be capable of performing the technical cloning treatment, but not the mental health elements of the post-treatment.
DOUBLE EDIT COMBO:
For sake of this discussion, it may be a good idea to separate the intent of the changes from how they affect existing characters. Compelling you to change who you play in order to adhere to the employment qualifications or the "play believable characters" rule is not why these guidelines are being updated. We are trying to create a foundation of believability and agree on a set standards for the future, in a field where those standards can differ significantly around the world.
