If your wife is in valid H-4 status, she should be eligible to file a change of status to J-1 with USCIS. These type of applications usually take at least 3 months to be adjudicated by USCIS. If timing is an issue, you may consider having her apply for her visa at a U.S. consular post. Also, before applying for the J-1, you should check whether she will become subject to the 2 year home residency requirement.
I recommend consulting with an immigration attorney regarding these and other processing issues regarding the J-1.
