I would like it to go this way:
Bruce marries Selina, they have a child named Thomas Alfred/Richard Wayne. First name is in honor of his father, and his middle name is in honor of the one of the two family members that never were blood related, but were family nonetheless. I'd like Gordon to still be Commissioner (unless he's dead or something that I don't know about). If he isn't Commissioner, Bruce could be, but then again, how is he going to be put in that spot without having even been a cop?
Dick becomes Batman and rules over Gotham.
Jason becomes Red Robin and takes control of Bludhaven (or helps Dick in Gotham).
Tim is still Robin, and he goes either to help Jason or to help Dick.
As Thomas gets old enough, Dick trains him, eventually having him become the new Batman as the years go by. I'd like to see Bruce and Selina have a daughter as well later on down the line, maybe when Thomas is 8 or so, and put Martha and/or Barbara in her name, whether it is the first or middle name doesn't matter to me.
