My only two cents is that pour hot wort can cause hot side aeration. if you believe in the harm HSA can cause, then you can't accomplish your first question.
Also, you need something like 10 minutes of 212F to sanitize/sterilize. the heat lost while putting it in the conical means you wouldn't really sanitize it.
I'd prolly use Star-san in a spray bottle.
