It wouldn't surprise me if sooner or later DC collected ASS as a TPB.
The ASS acronym was discussed by Thomas in the letters pages in one issue. You get the impression he hadn't thought about it.
I liked Thomas' work on ASS and Infinity Inc, but didn't read any of his other stuff, other than one of his Thor stories where Balder gets shot and dies as a prelude to Ragmarok.
I gave up about 10 or so issues after Ordway left: the new art wasn't so good and the stories started to lose momentum.
