For just message-passing, I think it'd work basically as expected. The only concern I'd have is if you ever need to retain specialized Android objects across RPCs. Many Android objects are special and are only serializable over Binder. gRPC Java does have Binder support, which allows passing these between processes. While gRPC C Core used to have Binder support, it was removed due to lack of maintainers and usage. So there's not an implementation to transfer these to non-Java.
If you end up having to deal with those specialized objects, you'll need the Java process to hang on to them for the non-Java process or design the RPCs such that the object doesn't need to persist across RPCs.
