Personally i'd love a Batman and Robin series with Dick and Damian. You know, less grimdark, more action, more fun, flying batmobile, zanny villains, and all that.
They could easily ignore Bruce but i guess that kids would nerdrage just as much as we did when they find that Bruce isnt the one wearing the cowl. So they can summarize his fate in the first episode and then explore it further throughout the series as B&R find more about what happened. Bruce will return at the end of the series. They could even dedicate some episodes to him and show his adventures through time!
The thing is that Dick and especially Damian's origins need to be set up first. You cant just tell kids "look, the old Robin grew old and is now Batman and Bruce's kid is Robin". Kids will be like "WTF man? Who are these guys?" (because i doubt todays kids have watched BTAS to at least know Nightwing). So unless they have a Batman animated series or movie that sets everything up and culminates in Bruce getting Omega sanctioned, B&R wont be possible.
