I think you are technically on the right track but the point of whole discussion was that most of Photoshop's functions / tools are not geared towards 32 bit matte painting workflow so we were trying to find a workaround and also it was more to do with LOG images which is a different ball game compare to 32 bit linear CG render.


PS: Btw, have you tried LayersLayers tool by Zach Mandt? I think its solves the whole issue and now my only complain is when Photoshop will support .3Dlut instead of ICC color profiles? :D
