Welcome to Librarium Online!
I started with the Basilisk kit, lopped off the barrel proper and put the breech in backwards. Then I extended the the new barrel with a multiple rocket pod casing from the Valkyrie kit (I didn't need them because I converted it to a vendetta). The result is a little cartoony, but it is difficult to avoid that with a weapon of this nature (gigantic siege-morter). It will be interesting to see how close it matches the actual kit if/when it is released. Questions, comments and suggestions welcome.
don't think the barrel is big enought for a colossus, but it certainly makes a good medusa.

(U) I think the barrel is fine but the breech is much too small. Google both of those and you'll find that the medusa and collosus both have slightly larger barrels (over the earthshaker) but the collosus has a much larger breech.
