I'm not sure about compatibilty of differently compiled binaries (different --configure flags, different compiler/version, different PG minor versions), but I think that could work..
As I mentioned, you could also EXTRACT the PGDG postgresql10-plpython files without installing the -server.
Or you could compile+install the plpython extension. I'm not sure but I think that would be ./configure --with-python.
..However if it were me, I'd schedule a time to stop the server, move the custom-compiled binaries out of the way, and restart using the PGDG binaries pointing at the original data dir. I think the only condition for doing this is keep the same major version (10) and to avoid lower minor versions (eg. once you start with PGDG 10.4 binaries you should avoid going back and starting with locally-compiled 10.3 binaries).
