After Watching Rogue One For The 20th Time I Thought How Cool Would It Be To Go Into Battle With Director Krennic's Unique Ship. So What I'm Asking Is There A Ship I Can Modify To Become It Or A Chance They Will Release It Officially.

The Titanium series die cast model is probably the closest official model you'll get (Here). It's a little under scale but probably close enough to look OK at tabletop distances.
