Idea once Yorick/Mordekaiser get reworked

I don't know about you guys, but I love the pentakill skin line. Unfortunately, some of the skins are abysmally underwhelming, given their rp price. Mordekaiser's is 975 but it is literally just a model change and yorick's is also ** 975**, but it just gets a little animation at the very end of his dance. Karthus is 750 but it gets many new voice lines as well as an amazing new model. When yorick gets reworked, I think that the skin should either get a lowered price or be updated to be worthy of its price. Another thing that would be awesome would be a pentakill event similiar to the PROJECT skin event. The music could be songs from Smite and Ignite or maybe even new pentakill music, where each member with the pentakill skin's instrument(s) are heard instead of the standard summoners rift music. For example, you had a pentakill team except for karthus it would be a pure instrumental without vocals. Pentakill minions would also me pretty awesome. What do you guys think?
