Ok, so the strat is to use Unity Asset Bundle Extractor to extract all the textures from the modded sharedassets files, keeping in mind it has to be installed in a 1.0.5B build to work. You then extract the textures from the 1.0.5B build you're going to use (or a vanilla 1.0.5B Dev) so you know what to rename the modded textures to. Finally, you use Unity Asset Bundle Extractor to Edit the affected textures, replacing them with the modded ones, creating a single sharedassets file with all the modded textures of the build of your choice.

If that sounds to confusing, I'll be happy to take requests to combine/port mods as asked.
