Greed and envy are covered by the Hunger demon - envy being a coveting of (or a metaphorical hunger for) what someone else possesses, while greed is a hungering for just plain more - hence why it's not called a Gluttony demon. So it seems more likely to be other, less obvious, negative traits.
That's how I've always interpretted it as well, however there is some room for severability if they wanted to expand the hunger demon into three different classifications for the sake of enemy diversity. Desire is sort of mushy as well because while their appearance goes to lust some of the experiences with them do not. The exiled prince one, for example tempted Lady Harrimon's envy.
Towards Maria. I'm not sure what they meant but what you listed would be demons for actions where the motivation would already be covered. Patricide for example would most likely be an act of wrath, or possible envy I guess, but either way the motivation already has a designated trait. I suppose we'll have to just wait and see but trying to inject something into a set of qualities that pretty much every civilization has coalesced around, and which provides the basic framework from which this franchise draws heavily seems like a quagmire that may be best avoided.
