If the older heroes of the Justice League were to retire, who would you expect to see in the next generation?

Let's say the original founding members of the Justice League and any other, older heroes that joined them all decide to retire. What heroes from Dick's generation would you expect to see take up the responsibility of continuing the League?

I'd expect to see this roster or some similar variation of it:

• Dick Grayson as Nightwing and/or Batman
• Kara Zor-El as Superwoman
• Donna Troy as Wonder Woman
• Wally West as the Flash
• Kyle Rayner as Green Lantern
• Garth as Aquaman
• Roy Harper as Red Arrow
• Barbara Gordon as Oracle
• Cyborg
• Starfire
• Firestorm
