Imperial Airship

So I have always wanted to build an Imperial Airship, but I have never had the right pieces until now. 

Here is a quick concept (forgive my paint skills). 



The idea is that it will be an escort sized atmospheric gunboat... 40k scale. 

I originally planned on making an airship "count-as" marauder. But I felt the marauder lacked that umpfh I felt I needed. Think of this thing as the Imperial answer to a AC-130, but with AA capabilities as well.
