Yeah, interviewing them would be a neat idea!
I also think they'd be easy to find.
These articles offer some good insight on what it was like to be a part of the Toronto indie scene in the early 2000's, and offer a glimpse of how the media portrayed this scene - speaking to some old members (musicians) about their experiences would be quite interesting! They're competent folk, and I'm sure they'd have a lot stories to tell us, or wisdom to share.
(That's the optimistic view I hold, at least! All in all, it comes down to me being a big fan, and wanting to find out more about Metric's very early past...)
