You should port them to 2nd edition if you find the time.
Perhaps I will! I admit the thought occurred to me lately, too...
In the past, I also thought about writing a unified ruleset for all characters, or an Only War-supplement for Sororitas campaigns, but I think I would bite off more than I can chew with those ideas. An alternate "add-in" rule for Acts of Faith, on the other hand, should not be longer than, say, 2-4 pages. Much more doable, even with my erratic bursts of enthusiasm in-between periods of laziness, and the limited spare time I have at my disposal.
As for Inquisitorial investigation, sounds like a Sororitas ran investigation that has the capability of drawing the ire of the ordo hereticus for any hiding and covering up of evidence.
Hah, now it really sounds like the start of the Daemonifuge graphic novel!
