Utilizing the spare wheel pit

Hello, from next week I am also proud owner of a 2013 V6 FSI long. I noticed today that he doesn’t have a complete spare wheel but only the breakdown set on board. This is in a powerful foam thing together with a trailer coupling that fills the trough virtually completely. Is there a reason not to rebuild it and let the space benefit the trunk? That’s always quite a lot of volume which I could use for longer tours with the family well. Maybe there’s already a solution for that.
