True, the Warner bosses have way more say than the writers, but I don't think they're idiots. They probably talk to the writers. If the writers say they don't want to lose Arsenal because there's still stuff they want to do with him, the bosses would understand. They're not going to uproot two shows to plant another one, y'know?

I know this is all theoretical on the idea that these shows decide to work together but bare with me. Don't forget about the people that pick up Titans without even touching the CW shows. Introducing two new characters to the show and being told, "hey, you know these guys! They're on these other shows you're supposed to be watching, too. Like them!" wouldn't really help Titans at all. It would just leave two developed characters on the back burners, hanging around solely to appease fans of both series.

Single episode visits, like Arrow on Flash or vice versa, work because they're just that: visits. You can keep watching your series without missing anything.
