I tried it and then applied your suggestions, I couldn't get it to be stable. The chains solved fine without too many substeps even, until I put the weight on it causing the chains to either stretch or jitter constantly.
Was worth a shot but I went the embed way, since I did not want to compromise on the density of the bag, much more efficient of course.
I would like some more wrinkling on the bag, I was thinking of adding a cloth layer to get there.
