Welcome to the board! I don't know how much of the light purple you have, but I would put all the cupcakes on the same light purple background, then go with one or more of the dark purples for the filler blocks. A possible issue is that the cupcake die is not large enough to display the print (like the ravens logo). Looks like the base is about 3.5 X 3.5". So another option would be to fussy cut the prints to 4.5 or 5" squares (looks like you have a charm pack in there), then use a couple of the solid purples to border the blocks.
