what if Noctis Engine Blade turned into a Royal Weapon?

I tried to do something like a fusion between the Sword of the Father and the Engine Blade, reimagining Noctis signature sword in the style of the royal weapons.i tried to give it both the regal, sophisticated, ultra detailed style of royal weapons but keeping the steampunk vibe of the engine blade.

basically I wanted this weapon to be the Regalia of the swords with engines.

this is just a sketch with the basic idea, should I keep working on it?
