That became a problem once they ended up on different networks though, plus that whole Superman already exists and has been active for years thing doesn't particularly mesh well with the Arrowverse, I'd imagine if the CW hadn't passed on it we'd be looking at quite a different show.
I do hope going forward that they'll be a bit more open to cross overs though, especially since it did decent numbers.
