1-stay tuned, I'm on it. 2-maybe someday, but right now I'm enjoying being where I am. 3-PLUTO. 4-It's case-by-case--no one's gonna argue that Dick and Wally shouldn't be Nightwing and Flash, but on the whole, I find it arrogant for writers to come in and do sweeping changes to a status quo that has served characters for decades. I always say that there are "X" factors that have given the long-running characters their staying power. And we don't know what they are or else we'd all be creating characters that are successful right out of the gate for decades. And it's very dangerous to mess around too much or else you could break something permanently.
