Well, I'm not entirely sure which arenas could host NHL hockey without much effort, but I'm pretty sure the arenas in Atlanta, Cleveland, Houston, Milwaukee, Minnesota, OKC, Orlando, New Orleans, and Portland at least have proper hockey configurations among NBA arenas that don't already host NHL teams. Kansas City's new arena was built that way as well. (No, the renovations to Atlanta did not remove the ability to host hockey, even if it's unlikely any time soon. They would need to rebuild the Thrashers former locker room, though, as that space was repurposed in the renovations.)
Among the other NBA arenas, Brooklyn, Charlotte, Indy, Memphis, Phoenix, and San Antonio have ice plants, but with the off-center configuration found in some basketball-first arenas. (Utah's arena does have a centered hockey configuration, but it requires a lot of retractable stands on both ends; it opened slightly before Phoenix pioneered the off-center configuration that's become so common.)
Meanwhile the NBA arenas in Miami, Sacramento, and for Golden State (both their recently vacated home in Oakland and their new place in San Francisco) don't even have permanent ice making equipment; when Disney on Ice comes to town they use a portable ice plant in those buildings (and those shows don't need a full NHL sized rink). Same with the arena in Louisville that was mentioned above.
What it comes down to is that concert tours and such expect the 200 x 85 foot floor space of a hockey rink, as the equipment and stages are designed with that in mind, so these arenas can open up to that size when needed, but since they want closer seats (especially in the upper decks) and sightlines maximized for basketball's smaller court, they minimize the movable seats by only retracting on the one side. Not an issue for stage shows as the retracted side simply becomes the backstage area that is closed off during the show. In fact, it actually minimizes the amount of lost seats in some ways.
However, as any Islanders fan (and longtime Coyotes fans from when they first moved to Phoenix) will tell you, it makes them useless for NHL hockey, as the seats on that retracted end are obstructed by the overhang. It's passable for minor league hockey, as those seats aren't needed, but even there the minor league teams in Charlotte, Indy, and Utah opt to play in smaller rinks instead of the NBA arena; only the San Antonio Rampage regularly use the off-center configuration, and that's because the team is outright owned by the Spurs' ownership.
