Not happening. Showare already hosts the Seattle Thunderbirds and Tacoma Stars, not to mention high-profile concerts and shows (where they make their REAL money). These venues aren't charities - they're private businesses and are actually pretty expensive to rent out. One reason the WIAA stays in the dome is it's cost effective to have everything under one roof.

As we've seen with football and gymnastics, if wrestling leaves the dome then state will likely be taken to high schools.
