I know its an old thread, but have been away a while.
Must try the Babs stock replacer, have been using HGEC_stockcloth_armor_replace_11norm_ver2-18641, which is an adult version but easy to install (just copy meshes/textures over).
Have three versions of Nehrim going (needs tidying up soon), HGEC with Roberts male, Roberts Male and Female and TGND (HGEC works well with TGND (apart from needing replacement hands and feet sometimes)).
All the armour and clothes which I have converted to use in Nehrim (not uploaded but for my own use) work well, but it is noticeable that some look rather dated/dull, think this is due to the ammount of detail incorporated into Nehrim armour etc.
