Buffo: why not use the rules for SoB out of the Inquisition handbook or better still the Blood of the Martyres, whis is what im doing.

Comparing the SoB from both books, i would rather from Blood of the Martyrs, its set in a flowing order with options for Celestiens, Repentia, Seraphin, Fabulous and Dialogus packages. Think they will enjoy those rules more than modified SM rules.
Besides the list of Faith options is over 20 now, instead of about 5.
