Saori Bidoof and Ari Bidoof are available in trade circulation, I think some of them might be posted somewhere on this site in gen 4 pkm format. They're fairly common, I have them but I'm more of a trader and researcher rather than posting things for free.
During my research, I can tell you that most Norii Bidoof and Ori Bidoof you'll find are fake. The Norii Bidoof was lost in time to the gen 4 traders, I've been trying to contact them myself since some were friends I used to know, but I haven't gotten any response. Ori Bidoof, I know of only 1 person who has it but they don't trade their pkm files anymore.
