The risk with such a gravity engine is to obtain non homogeneous granular assembly, as with isotropic compression. This is the consequence of arching effect developed by a granular assembly (even with vanishing inter-granular friction angle). I think the best is to find a process homogeneous "in nature" as the compression by growing grains, or maybe, the Janek's StaticAttractionEngine (I have never tried).
