Adding a new PVP mode and a handful of new items to grind for doesn't solve the issue of replayability. Even games like Halo features 8v8 BTBmatches, and they still followed the normal ebb and flow of a traditional FPS. It wouldn't make the game instantly more replayable and instantly bring back the magic D1 had. If they want to bring back the magic of D1, they can start by abandoning their current approach to the game, port over everything from D1 - subclasses, loadouts, gear, etc. (since the new loadout system is gone there is no reason to leave behind everyones favorite stuff), add in RNG-lootbased incentives to replay the game, update the old subclasses with some of the newer abilities people like from D2 (replace Defender's vanilla Ward of Dawn with the Captain America shield ability), Have balancing roughly similar to HoW in PVE and PVP, separate Trials off from the rest of the game in terms of balance and gear, and that's just a start. But I can't even imagine them taking SOME of these steps with any of the first 2 DLC's because such changes represent a major overhaul. I don't think they will simply abandon their quest to make Destiny an Esport after a single month. They'll want to try to see how it pans out in the long haul, meaning significant, substantaive, and substantial changes will not come until their first TTK-like DLC, scheduled to launch sometime in late 2018. I've been wrong before, but I'd bet on the game not changing substantially until then, if at all.
