Cool Religious or sentimental traditions ?

Hi everyone I recently saw a really cool wedding video where the bride and groom washed each others feet during the ceremony as a symbol of humility to one another. (Also represents the religious symbol of Jesus and a few stories in the Bible ) I wanted to add this to my ceremony but I feel like it may not be enough room for all of that in my church. I want us to do something symbolic and similar to this but something needing a little less accommodations may be better. Any suggestions?
