I've managed some time to come back and update my core mods. They now come in the form of packaged game pcc files. You use them to replace the original game pcc files and then update your game and DLC pcconsoletoc.bin files with ME3Explorer. Instructions in each package.
I found a Tali face texture I liked at DeviantArt and stuck that on my Tali Face Mod mesh model. This is a 3ds render with the visor in place. Eyelashes are not final and need final correction in the texture.
