Of Course I would do this.
The idea is simple. get two Iowa class hulls(Discards to the round file) Now sand the edges of the top of the hull to a straight line. Of course you have removed the decks and all that stuff. Attach both hulls together at this seam.
Now take the Citadel from the deckhouses on Both and attach them to the sides near the bow. The rest is up to you. You will have when done, a Corellian Tanker or whoever's. Or it can be a space-going Beer Tanker from Heinecken ! A Water Tanker from Atlantia ? Your choice again.
Or this. Take some springs out of some pens. Put a plastic rod that fits tight inside of them and taper the end mounting a round bead on the sharpened end. You can place these all over like Porcupine Quills but they are actually Proton Cannon.A super Space Dreadnought!
Because of the flat bottoms you can cut openings for hangar bays for the aforementioned Firefoxes. Remember the top and bottom of the new ship were the sides of the originals.
