While I am more than willing to test this setup out for my brother on a
pair of CB radios, I told him I might need an STA from the FCC to
communicate data on CB channel 40. He tells me that in an emergency,
anyone can use any frequencies they want, any power, any mode. I told
him true, but that does not help me as an OEM getting fined for testing
out an emergency scenario in a nonemergency situation.

I think you're correct. Part 95, section 631 (c) and (e) and (f)
make it quite clear that data transmission over CB is a no-no.

In addition, the simple act of hooking up a data transmission circuit
to a CB radio's modulator might be considered to be enough of a
modification to void the transmitter's certification.

Applying for an STA certainly seems to be the safe thing to do. And,
if you get one yourself, the end-user agency should probably also get
one, so they can run periodic tests and drills without breaking the
rules.
