CP0018 100mm swap for 80mm

Seeing canyon isn't selling these cp0018 cockpits to folks, I am looking to swap with someone needing a longer one. Wife's bike has too long of a stem and I'm running out of options other then buying another bike. The 80 and 90s use the small bar ends and the 100 and up use larger ones. So I would be wanting to swap the Cp0018 with bars for the same but in 80mm.
