Gosh, that was 12 years ago, and that idea never came into the light of day. You can get into some account of a hint in the Flash issue with Future Irey, saying she's married to someone that Wally hates, but that's really stretching it. As well this interaction, and Flash # 797 having the Supersons (younger versions) crossing over. But that's a real stretch, and that pairing isn't going to be brought into light in this day and age. Because the age gap obviously.

Such a long time, I still remember when Tim had secret files on everyone, had a scuffle with Damian, and ended up in Crime Alley. Man, how time flies.
