This sounds good!
I'd go one step further and get ALL the older quests functioning on the newer quest engine so there is only ONE list of quests you are on. This may fix some of the bugs with the older quests that seem to keep people from progressing in them.
I'd also suggest that most quests be made repeatable, since none of the loot is overpowering.
Lastly, make the daily quests reset at server up, not 24-hours-and-change from the last time they were done. Keeping track of that isn't fun.
We made a lot of strides with the Ararat quest with regards to getting some basic tasks fixed into a working system behind the scenes. The next step is to unify all of our quests under a more intuitive, and functional system that we can quickly add to, maybe even with the long term goal of providing a player usable means of developing a "quest" within the world. I've been on some pretty clever player made quests before that utilized a variety of in game features and some fancy decorating that were quite enjoyable. I think expanding on those abilities would be pretty cool. We try to offer something for everyone in the way of quests and are all for making them repeatable without making them feel too "grindy". If there were certain aspects of the Ararat quest that anyone was particularly fond of in terms of the interaction (conversation menus with NPCs, quest items that gave clues about their description, Easter eggs, etc etc) or if you felt something was particularly missing that feedback would be exceptionally useful moving forward.
