Help complete “the Complete Elfquest”

As (we hope) you know, Dark Horse Comics has published two gorgeous volumes in their “Complete Elfquest” series. These books contain, in the first collection, the entire original 20-issue quest; and in the second, all 17 issues of “Siege at Blue Mountain” and “Kings of the Broken Wheel.”
Those were the easy collections! Each book contains totally linear story. But now, as Warp and Dark Horse contemplate further volumes, the question becomes “In what order should the later tales be read to make the most sense?” For a while, Elfquest split into concurrent tales (Cutter’s Wolfriders in “Shards,” Ember’s in “Hidden Years”), as well as past and future threads.
