I can have a look.

Currently, `package-install-file' reads the package contents into a
buffer and calls `package-install-from-buffer' to parse the headers,
download & install its dependencies, and finally install the package
itself from the buffer.

Just to confirm, what we are discussing as a solution (at a high
level) is to parse the package headers from a decoded buffer, download
& install its dependencies, and copy/extract the package file to the
elpa user dir?

Thanks
