I can build you a false wall for that purpose. My company, Hole In WalI inc. has built many such walls over the past 2 decades for Clemson Basketball fans.
Estimates run $4OOO-5000 for the real deal, sheetrock and $$2000 for cardboard designed to look like sheetrock. Wall has a one season life and my Co. Is not responsible for any injuries to user. We can also construct a kiddies wall for those responsible parents who want to prepare their kiddies for becoming future Clemson BB fans.
