No. Since Own Tempo is a special event ability it won't work like that. However, if you had a female Tough Claw Dusk Lycanroc and bred it with a compatible male Pokémon, there would be a chance the off spring could get Own Tempo. If you had a male Tough Claw Dusk Lycanroc though, you would need Ditto to breed with it, again there would be a chance the off spring could get Own Tempo.
But since you missed the event, You're out of luck. Don't you have a friend who could let you borrow their's?
