I definitely agree. DA:O and DA2 also had elements of the intros that came back to resolve later, and it worked really well. It could be anything, but maybe something as simple as people mugging you, then meeting them again after you become the Inquisitor. See the terror in their eyes as you exact revenge! Or forgive them and have them learn something! Maybe they were just desperate and now you can give them a leg-up in exchange for serving in the Inquisition! It's up to you! I'm just thinking outloud... 
Edit: And obviously that wouldn't be the entirety of the content, just a loose thread to resolve later 
I'd go a bit farther than a mugging, but I'm kinda dark with stories and such. I'd strive to leave my companions speechless - put Blackwall's backstory to shame.
For a Dalish character (since elves are my favorite race) I've been thinking something along the lines of the clan being terrorized by either the Mages or Templars (the opposite of whichever faction you recruited/conscripted though Templars are more likely since they're Chantry-raised, prejudiced bullies) early in their stupid war. Perhaps it's revealed that our beloved elf was something of a ghost story - like killing any Mage/Templar that entered the area on sight and the area was thought to be haunted and therefore avoided by all humans. And since the Mage Templar War has been on for a few years, it's not impossible. The Keeper finds out and sends you to the Conclave to get you to let go of your hate. If you don't let go in the midst of all those Mages/Templars - you're sure to die.
After the telling, companions may comment on the tale individually - awkward conversation ensues with some. Lol Akward can be fun.
