Do the 3 modifier prizes at end of the 3 raid boss levels stack?

[Mil Mascaras]

If someone picks up multiples of the big 3 prizes with modifiers, do they stack? Do the a/d numbers stack and does the modifier stack? I'm thinking the a/d stack but not the modifier. Anyone know? Anyone.... Anyone .... Bueller?
