I know that CEM will not work exactly properly since it needs english texts to actually skip certain lines. On the plus side, Autoola made a German translation. https://www.nexusmods.com/masseffect3/mods/722 He has CEM and the transition mods for use with CEM. MEHEM is also covered by Autoola https://www.nexusmods.com/masseffect3/mods/736 As for the rest, if the mods say English only, then unfortunately, go with what they say. As far as figuring out if things conflict or not, right, it's very difficult to figure it out. You'd have to manually install all of the mods and then compare the files to look for duplicates. In general, if you don't see duplicates, you're fine. The exception I know of is PEOM since he streams into custom file names during the end (JAM and others do this as well but on your list, PEOM is the only one I know.) If the Hairy Sheploo only has a few files in it, likely you're fine. Omega Hub should be ok if it supports non-English. Ditto for Tali. I doubt EGM supports non-English but if it does, great. ALOT and ALOV definitely should be fine and install it last (and yes, install any CEM Full or goodbye patches after ALOT, it's an odd deal that's a thing on my end.) AmbientAudio might... depends on what they changed. That's my thoughts anyway and lots of guessing. On the plus side, MEHEM and CEM have German versions thanks to Autoola.
