Optics for SF Rifle Set Up

[Dead_Fred]

Hey guys, finally managed to finish by Leonidas rifle and it looks mint but I'm thinking what optics to have on it and I'm after pictures or ideas for what to go for, I want something a little unusual to match with the gun, so I'm currently thinking a 4x ACOG on top and then with a 1 o'clock mount with either a doctor sight or a reflex style sight but not sure if it would look right.

So ideas please
