Is there something that makes this currently impossible or just that the user would additionally need to download Bro source code and tell bro-pkg where to find it before installing a package where the build_command will build a plugin?

I wonder if pre-built plugins can’t already be distributed in packages? E.g. put the pre-built plugin in the package, specify its location via plugin_dir, and leave the build_command blank. Then after the package is installed, I think Bro should automatically try to load the plugin, provided the architecture matches.
In other words, I think bro-pkg is already set up to handle distributing pre-built binary plugins, but the more difficult problems to address will relate to how to actually produce plugins that will be binary-compatible w/ a user’s Bro installation. E.g. lack of stable/standard ABI in Bro and C++ itself means there’s myriad ways to produce unportable binaries.
The only other idea I have, is if bro-pkg is not able to locate Bro source code (i.e. the user installed Bro from a binary package), then it could automatically download the appropriate version (e.g. clone Bro’s git repo and checkout a specific version tag).
