I vote no. To me, caresheets are things written about keeping pets, and I disagree with the keeping of venomous snakes as pets. Those facilities and individuals with the justification to keep venomous snakes, and the experience to do so in an appropriate manner, will not need caresheets.
My opinion aside, however, the main reason you don't see many venomous species caresheets is the legitimate concern about liability. If you write something, or publish something, that says 'this is how you keep a cobra', then you are painting a big legal bullseye on yourself in the event that someone reads your info and then gets envenomated. I'm not saying that it can't be done in a manner that would minimize your liability exposure, but it is potentially a servious problem. If you proceed, I suggest you do so very carefully.
