Yes, that works well.

We actually have that in place already. You can hook in as many shell
scripts as you want, like this:

ExecStartPre=/some/shell/script/to/run/before/the/daemon
ExecStartPost=/some/shell/script/to/run/after/the/daemon
ExecStopPre=...
ExecStopPost=...

You can easily do that, simply by renaming the .service file.
