Seasonal Decorations

I love seeing the items in the cities for each event, Its always something to look forward to!
HOWEVER with the rise of personal housing I was wondering is we could get some of them for housing? The black and purple decals are so awesome I'd love some in my house, as well as the pumpkins in my garden!

Not just Halloween but can we have a selection of items from each seasonal event as either craftables or buyables during the event?

Like the items from the summer event, only more?
