How can we get everything in PBE ?

Today I bought 25 Cursed Capsules and finally managed to get into point where I dont get Skins from Hextech anymore. Now only wait for RP Refill fix to get remaining skins. BUT how am I and we supposted to get the rest ? For example Victorious skins, Grey/Urf-wick, Black Ali and more. They are either unavailable or cost 99999 RP. Is there even way to get them ? There will definitely be time when Janna or Kayle get reworked I would like to test all their skins.
