You can't file to extend her visitor status and file an I-130 at the same time. (Or, you can, but it won't be approved the filing of the I-130 for her will show immigrant intent, and to extend the visitor visa she needs to show non-immigrant intent). The I-130 alone will not extend her valid stay in the U.S. Filing the I-130 and the I-485 at the same time will allow her to remain in lawful status while waiting for the adjudication of both.
