SkyRe is an overhaul not only for perks but many other game aspects. Getting other perk overhauls w/o conflicts is a bit of a fool's errand. You can use other mods that modify perks, but they will overwrite each other. And it will be up to you to decide which one will ultimately apply to your game. As Davin pointed out to use SkyRe you will need the Reproccer and appropriate compatibility patches for your weapon/armor mods.
