That's certainly plausible when considering how the Breen are commissioned for various jobs. One could theorize that the Dominion had commissioned the Breen well before officially entering into an alliance--alluded to in The Dominion War Sourcebook, but the only clue in canon was Yelgrun's remark, "And I thought the Breen were annoying."
As for the newest Typhon Pact books, I've fallen a little bit behind on TrekLit after the first four TP books. Then throw in that the Barnes & Noble closest to where I live doesn't keep up that well.
