That's a cute idea.. (but then I just love The Godfather!). One thing though - I wouldn't put "Faithful unto Death" on the shirts because that is Tri-Sigma's open motto.
But I like the "We made them an offer they couldn't refuse" for bid day shirts, hehe. Very creative!
Delta Chi doesn't generally theme our bid days, but we themed last year's skit night as "Taullywood" (Hollywood). It was so cute (we had a red carpet and everything! and we gave the rushess popcorn and candy and cokes for while they were watching the skit
)! You could do something like that for bid day and give everyone sunglasses and treat them like stars or something fun like that.
(PS - When we were popping the popcorn for skit night, the microwave caught on fire! Good thing we did it early... we had time to air out the room / borrow a sister's microwave... but skit night was definitely a... blast!
