I'd like to see an entire Mausoleum at the Tower. For all of the fallen guardians from the nameless to the infamous. Kabr, Dredgen, Eris' fireteam, etc and include scannable Tombstones. It should be a big deal and a good way to get some of that grimoire into the actual game. They could even hire the Guardian Radio guys to do holotapes that explain their lives and deaths which would get the community more involved. Let us leave offering for a small boon maybe. I'm sure they could have a small crew accomplish that. Hell let some interns have a crack at it. Perhaps even turn it into a Crucible map with Class Clash (maybe mayhem style) with 3 teams set by the class they play as (hunter, titan and warlock) just as an homage. Edit3: A couple more small ideas to add to it, bounties to honor each of the dead and statues for the elite.
