I think most (many...uhmm ....atleast some) can agree that destiny needs some more pve stuff, the queen's event only lasted a week (or was it 2? i forgot) and now's a good time to come back, normal shards and energies are far less important so having them gained from queenstuff wouldn't realy "boost" anyone higher than 31 with some weapons to use for the raid(s), and people always want shaders, emblems and guns/gear with unique designs (atleast the ones i know). Then again instead of throwing chestpieces etc. at people you could make them special rewards for rank-ups or specific tasks (like eris's missions like the urn maybe) that makes them a bit more unique and it would feel more like actualy helping the queen instead of a "kill 200 random fallen for some exp." deal
Another idea would be adding specific special event-enemies like with urzok but those only apear in the time the event is there, highly trained fallen or maybe getting attacked by a archon/spiderwalker, on some of the bigger areas after you did some objective or killed too many fallen. (they could try to set up a camp for example, kill their defenders and they get reinforcements)
Other ideas are appreciated
P.S. (also please find and correct my bad grammar... i don't want that in the way of the idea)

Your ideas are pretty good, it's a shame that it hasn't come back and won't for a while, I really liked the gear.
