@El Mahdi Good post and that is pretty much how I interpret as well. Very much a la the MHRP or FATE malleable "stressed out" such that we can skin the incapcitated combatant in a number of ways. Interpretting HP in the above way and "unconscious" as "stressed out or incapacitated" has always allowed our table a wide swath of diverse narrative renderings (to both the incapacitation and what comes after; eg capture and Escape from Prison trope!).
I think @chaochou's quality suggestion of an "emotional stress track" and/or "mental stress track" as siloed modules to track these states would certainly be helpful. I use the Condition/Disease Track in 4e regularly as a method of attrition that can prevent Extended Rests (and Short Rests) when I want difficult environmental treks (eg lost in a winter or jungle wilderness) to be a theme for the day's play. It does a great job of creating tension at the table and marries the mechanics to the fiction quite well. Its also suitable for horror themed play. I suspect (though I haven't tried) that it could be extended to a morale system in place of HPs. No reason 5e couldn't do the same. It would add a layer of "fiddly bits" that many folks (myself not included) may not like but if its functional enough with minimal overhead, it may get the requisite support.
