Has anyone based a battlewagon with deffrolla?

Afternoon Boyz! I've seen some really cool battlewagon with bases and I think it looks great but I haven't seen any with Deffrollas on? I'm looking to base my Deffrollas and wondered if any of you had advice on what base to use etc? By my eyes the biggest base I currently have (170mm) is too short.

Below is the deffrolla in question.
