Depends what you mean by recent, Barbara. In 1991, Paul Griffiths put together a whole lot of Mozart arias, some written for other composers' works, some just concert arias, some substitute arias in his own operas in a (rather boring) commedia dell'arte plot. It was called The Jewel Box:
Yes, I'd call that recent. I vaguely remember reading something about a "Mozart Project", but I didn't realize it had resulted in a completed opera. Boring plot, huh? Have you seen a performance?
