The cape and tanooki are both in the game, actually, for the SMW and SMB3 styles, respectively.
Here's an image of the objects that are in the game:

There are variants and combinations, too. For your flying koopas, you can take a koopa, shake it to make it red, then stick wings on it and it'll fly up and down in place.
Also, feather in SMW is tanooki in SMB3, copter shroom in NSMB, and amiibo shroom in SMB. Yoshi in SMW and NSMB is Kuribo's Shoe in SMB and SMB3.
