Can I play GTA 5 legacy with mods and keep the Enhanced Version clean?

Hi guys, I'm new here and after this big update I was wondering if I could play the legacy version with mods and don't worry about the enhanced version since now I will only play GTA Online in the new version and I don't have to worry about the mods interfering with my gameplay. Basically having mods in one version and keep the other one clean without any fear of, somehow, getting banned.
