Basilisk/Wyvern cannon sizes relative to Forgefiend?

[tinpact]

I had the idea to do an artillery Forgefiend a while ago, and now that I have one unbuilt I figured I might as well look into it. So, I was wondering how the sizes of the Basilisk and Wyvern guns compare to the fiend guns. The Basilisk gun is obviously quite long, but I can trim it down if need be (maybe it goes on top like an Exocrine? Something like this perhaps).

 

Also, any other suggestions for usable bits? I've got part of a Knight battle cannon somewhere, and I was looking at some of the Kromlech mortars.

The Wyvrn/Hydra barrels would be pretty easy to replace the Forgefiend guns with.  You could replace the head with a shortened Basilisk barrel coming out of the neck.

Ah, thank you!
