Getting a RC card requires product changing from another Bonvoy card; other threads cover this. That said, booking the club level with the RC Card requires a specific phone-only rate (Z38) and will not be compatible with corporate / event rates.
If you really want club lounge access for your wife during the conference, call/email the hotel directly about adding access for a daily upcharge.
