If you haven't already, you need to pick up the Avengers: Children's Crusade one-shot (that came out last April), where Iron Lad goes to a future where the Young Avengers are now the Avengers, and Kate and Tommy are together and actually expecting kids...
Be forewarned, it's a bit bleak and dystopian but it's great fanfare for Kate/Tommy shippers. Eli is actually with someone else too.
