This is my opinion on who they would cast, I tried not to let any bias in.
Derrick

Hayden
Dan
Frank

Kalia
Renny
Keesha

Daniele D.
I am a little iffy on Daniele D., Keesha and Shane. They could be swapped out for people like Helen, Shelly or Jeff (but I really believe that Jeff won't ever come back to BB because he works for CBS now.)
Comments
Jeff could always leave the house for a day and interview people
