Pentakill Yorick is Slash, Olaf is Lemmy, so is Morde inspired by Gene Simmons?

Both use Axe-Shaped instruments, both wear spiked Metal armor (sorta) and both got famous by their impressive Fretwork.
Too far fetched? Will Morde get awesome Plateau-boots in his VGU and Taunt with a sick Revenant tongue?
