However they have successfully released near complete run of Wally West's Flash series from issue #62 to #225 across 14 books (the Flash by Waid/Morrison & Millar/Johns) as well as a volume at the start of the run (The Flash: Savage Velocity of issues #1-#18) so hopefully that sold well enough to get the rest of the run (#19-#61 plus the post-Johns issues of #226-#247)

Likewise a large amount of Wonder Woman volume 2 and Batman post-Crisis has almost been completed

The Compendium format would be a good option to publish complete runs in a few volumes. So far, DC is using them for Vertigo or non-standard superhero fare (eg Robinson's Starman), but there's no reason they couldn't branch out into other titles.

And if DC wants to keep the Compendium brand for the more serious or mature books, they could use the same format and just come up with a different branding, eg All-Star Sagas. (If anyone from DC is reading this, you can have that for free.)
