I've been to a bunch of Tournaments, and those missile launchers would be fine at any event I've been too.
The swords should be switched out for something more 'glavey' though, but I'd see those pass at a bunch of events. You'll not do so well on hobby scores, but c'est la vie. Still, it depends on the events you're going too. Might still want to clear them with event organizers, just to be sure.
