Since a sideslip increses air resistance by essentially flying sideways, if I didn't know that it has been done, I'd say it might even break apart a (long, thin) plane that wasn't designed for it. And it still might, but at much higher speeds than close to landing.
It's not unheard of for airliners to use a sideslip when landing in a crosswind, so I don't think structural strength is likely to be an issue at landing speeds.
