I believe the conversion kit will work, but be aware, there will be a space between the dustcover and the frame.
The 92A1's slide is a bit different with the captive recoil spring. You can put a 92FS slide on a 90-Two and/or a 92A1. But not the other way around (no 92A1 slide on a regular 92FS).
So, the conversion kit should fit. But, it will look a bit strange. I'd really made for the standard 92FS or the M9A1.
