No interest in a Flamebird/Nightwing title (and the only way I wouldn't be pissed at its mere existence would be if the solo Nightwing book was cancelled)
With her brief appearance in 'Tec, it seems like Bette and possibly Harper would be part of the Knights when they come back together...but that just doesn't fit. Bruce is gonna be around no matter what, Tynion seems hellbent on forcing Kate into this book whether she's part of the team or not, Dumas is still around so JPV isn't going anywhere in the long term, Cass has a bunch of lingering plot threads and the garbage duo of Tim and Steph aren't going to be written out by Tynion obviously. The only one I could see maybe getting dropped is Luke, but even then he has his bromance with JPV and the fact that sending the only black guy to limbo while bringing in one or two more white girls wouldn't exactly look good.
What might make sense would be to continue with the current 'Tec set up until everything that's happened is resolved and the relationships Tynion wants to flesh out have been so. Then, when Batwoman and Batman Beyond are inevitably cancelled (I give them another year), replace them with books for Tim and Cass (The two best sellers of this lot), let Steph appear in those books, and have the new 'Tec team consist of Bruce, Kate, JPV, Luke, Bette and Harper. I don't really want the latter around but she's here.
