Emperor's children? (harder this one but I'd lean towards blood angels as they're both big time posers)
Word bearers: Also tough (blood angels have lots of chaplain options though so an Astorath list could be cool with death company as posessed)
Iron Warriors: CSM: with forgemaster, dreads & vindicators
Alpha Legion: CSM: An outflanking Khan list or (Grey Knights with henchmen as cultists)
Night Lords: Blood Angels Descent of Angels style
The key is to be creative with your theme IMHO.
