Far from an expert here. But just a thought. You could use wood shims to wedge the repair piece in place and tab in place from the underside. Then remove the shims, cover the voids left from the shims from the back side with painters tape. Use cloth as you described on the outer skin, when it starts to kick remove the tape.
The process you described sounds about correct to me. CSM cloth will make the sanding/grinding easy because you can tear the edge near the repair perimeter. Take some before and after pic's, would like to see how it comes out.
As far as over complicating the repair, even the smallest glass repair takes me longer than expected. Sounds like you have planed the process well.
