I think that would be the best thing in the case of his own personal saber and it looks very cool, I think its certainly worthy of the great Kaleesh warlord himself but if I may represent, being a huge grievous fan, this design was a work in progress with three years of refinements and it finally became complete. Actually I added one more slight change after this but this will do for now. Honestly though in the real SW universe yours would be more applicable to being his actual saber than this.

So I love yours but I wanted to show this too. I hope its alright with you.
