Have you ever tried Sims 4 Mods? There would be no conflict with Eve V1 as that is not a default replacement but a full body outfit.
It uses the same nipple locations on the UV map, at least as all the other popular nude meshes with nipples, so nipples should only be a problem if they're a problem with other mods. A majority of townies who will not be in the 90th percentile of breast size will look perfectly normal in a majority of clothing. Thank you, but is this affect default for all female sims, or just selected sim? What I really like to see is an increase in polygons for breasts because they look edgy.
I used the package from the evolved breast slider mod.
