Shower for 2Nd Baby If They Are Twins?

I have a 2 1/2 yr old son and I am expecting twins (boy/girl) in May. What are your thoughts on having a baby shower this time? I generally don't agree with having 2nd or 3rd baby showers but in this case, since we are having twins and one of them is a diff. gender it kind of seems to bend the rules. Thoughts?
