Friday night shower

I actually think it is a unique idea. I think it would even add more of a 'surprise' factor for the bride, considering every bride I have ever known knew exactly when their shower was going to be. I think if FH took me out on a Friday/Saturday, I'd have absolutely no idea what was going on, as opposed to an afternoon. I also probably won't be having a huge amount of people at my shower so for smaller parties, it could be a great time.
