I have seen many convoluted attempts to get around the testimony of the three witnesses,but they were as plain as they could be throughout their lives regarding what they saw and heard.
Book of Mormon, Ether 5:4
“And in the mouth of three witnesses shall these things be established; and the testimony of three, and this work, in the which shall be shown forth the power of God and also his word, of which the Father, and the Son, and the Holy Ghost bear record—and all this shall stand as a testimony against the world at the last day.”

"No man in this dispensation will enter the courts of heaven without the approbation of the prophet Joseph Smith, jun. ... If I ever pass into the heavenly courts, it will be by the consent of the prophet Joseph. If you ever pass through the gates into the Holy City, you will do so upon his certificate that you are worthy to pass. Can you pass without his inspection? No; neither can any person in this dispensation of the fulness of time. In this generation, and in all the generations that are to come, everyone will have to undergo the scrutiny of this prophet."
Now Normandy, if you want to go get Joseph Smith's approval, you will have to descend into Hell where the lying peepstone sexual predator false prophet resides with his father, the father of lies a murderer from the start. But I would caution you to give that trip your utmost consideration, to avoid it by accepting the Grace of God in Christ and be born from above, immediately, and repent of following this demonic religion of layered blasphemies.
If you raise up your children in this blasphemous cult, you will have placed around their necks a horrific weight to be removed before they can awaken to the Grace of God in Christ. Teaching your children that they can have God's Grace, if Joseph Smith approves of them is demonic inveigling. They do not have to wait for salvation until after all that they can do, they can be born from above immediately, whether you ever are or not. Do you recall what Jesus said about millstones?
