WWE originally planned to do a Chris Jericho vs. Dean Ambrose feud for WrestleMania 32 that would have seen Jericho turn on Ambrose, possibly playing off Jericho walking out on Ambrose and Roman Reigns at Night of Champions 2015.
Apparently several factors led to Jericho vs. Ambrose getting nixed, like AJ Styles coming in and Ambrose being put into the feud with Brock Lesnar. As noted, WWE's original plan for Ambrose vs. Lesnar at WrestleMania 32 had The Wyatt Family interfering.
