Perhaps it would help those you want to convince if you could point out
where in the BSD license that is stated or implied.

Let's leave compilations aside for a moment and talk about
modifications (derivative works). Okay?

I'm not demanding that. Preexisting elements of "its expressive whole"
remain under the BSD license. New expressive elements in modifications
(in the case of derivative work) fall under the GPL. Straightforward
way to convey that fact is to keep original BSD license on top and
indent the GPL below it with a notice that only modifications to this
file are under the GPL. The totality of copyright on derivative work
"as a whole" subsists of both copyrights (covering preexisting + new
elements).
