If i remember rightly there is a thread about this on the bioware forums.
As far as i know, you will only get in trouble if you use the mod while playing MP, some people get caught out because they forget to switch the coalesced file back to the legit one in order to play mp.
I've used mods like the above or of my own editing since my third playthrough and only in SP, received no warnings or bans. Play it careful, use only in SP and if worried play offline, its quite possible that several of those rumors were begun by people who used mods in MP deliberately or accidently.
I would recommend checking the official forums as such policies can change though.
@User2929, a while ago, a long while actually, you said you intended to finish the mod. Is that still on the cards?
