You had me at "Blasphemous Succubus Choir", and reading through it again has only emphasised what a cool idea this is - perverts, demons, hymnal singing oh my!
The mind positively boggles at the possibilities, especially due to its national influence. I don't mind the obvious sounding name, it gives the GM an immediate notion of the type of organisation, but more importantly gives ideas on how to present it in an exciting and original way. Fresh, easily customisable for most campaigns and good (un)clean fun.
Can't wait for the monster write-up (fingers crossed dude), really hope it's a winner.
