One-shot each for those specific holidays? If so, which pairing between Stardust and another for each holiday?

Can we pick any original ships?

April Fools: Either Rainbow Star or PinkieDust (Has them in a Prank War)
Easter: Twidust where Stardust introduces his Equestrian family to the Easter holiday, all aspects of it.
Birthday: PinkieDust; Stardust wakes up on his birthday and proceeds to be paranoid that Pinkie will pop out and surprise him, but instead, because she cares for him that much, she ACTUALLY does something low key, just for him.

Um.... Derpy x Star for Easter. My reason is that maybe Star helps Derpy when she acts very different then she dose very other day. And Star is wanting to find out why Derpy always act so different every time it's Easter.
