Bridal Shower Elope Untraditional Bridal Shower?

Untraditional bridal shower? - bridal shower elope

I threw my sister a bachelor party, and I want to make it unique. She fled, but I want them to do a special shower. The tradition is that you should 2 months before the wedding, but because there is no marriage is that you can bail before the flight? Once you do that? Any ideas would help!
