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.
Both EDI and Liara in game with default uniform mods. Liara was pretty fine as she was but I still took her closer to her ME1 form by reducing breasts, hips, and butt a bit. Did quite a bit of trimming from EDI's "ripe" body to make her more slender.
