I'd second the wiki idea. On CotH it was my main resource for looking up cross-faction profiles since my version of TRP didn't support reading their ingame ones. Of course that was only really convenient because it was mandatory, and since it would be optional here I bet basically nobody would use it. That's the drawback of any out-of-game solutions.
But what's the problem with addons? Is it that addon communication doesn't work cross-faction?
