Shower help/idea

So I had a boy in Aug 2015 and I am expecting another boy (confirming this Wednesday) June 2017. If I am indeed having another boy I don't need to have a "Shower" but want to at least celebrate the baby and let family give small things to the baby. I've heard a lot about diaper and wipes parties and sprinkles. Does anyone have any ideas of what we can do to have a small type shower to celebrate without making everyone feel like they have to buy something since we already have so much? We're not the greedy type who need a lot of things. Our son barely used most of his stuff and we saved everything knowing we wanted more kids.
