I was hoping much of Batman would be left alone.
I have mentally prepared myself for the Bruce/Dick timeline to make NO sense. It can't. There is no way for Dick to be in his early 20s and Bruce be 30 and have it work. Did 18 year old Bruce adopt 10 year old Dick? Probably not. This revamp is going to nuke a BUNCH of "Boy Wonder" stuff and replace it with a lot of "Teen Wonder" adventures.

I'm guessing it has to go something like
Bruce = 30
- started his training/travels at age 18
- started Batman-ing at age 22
- adopted Dick (15) at age 23
- went public to join JLA at age 25
- Dick leaves (Bruce = 27, Dick = 19)
- brought in Jason (17) at age 27
- brought in Tim (15) at age 28
- brought in Damien (12) at age 30
So, in present DC time, that would make:
Bruce = 30 (Batman for 8 years)
Dick = 22 (Robin for 4 years, Nightwing for 3 years)
Jason = 20 (Robin for 1 year, dead for 1 year, Red Hood for 1 year)
Tim = 17 (Robin for 2 years, rookie Red Robin)
Damien = 12 (rookie Robin)
That
seems to work. Dick gets to be a "Teen Wonder" from 15-19, then spends college years as Nightwing (with a little replacement Batman duty in those 3 nightwing years). Jason still has time for his dirt nap (no idea if Death in the Family is still in continuity), and Tim gets a few years as Robin before turning into Red Robin to "form" the Teen Titans. It also requires a very young Bruce (18) to get involved with Talia to create Damien.

But the timing does work at least...
The giant flaw with the timeline is how do you work Barbara in there? Let's say she's 21, close to Dick's age - if she has been Batgirl for "just a few years" as some interviews have said, then I'm not sure how she could have overlapped with Dick/Robin since he's been Nightwing fr that long in my timeline.
Arrg... I have to stop now, I'm only making my brain hurt...
