Uploaded! Although my question wasn't limited to my roster. I would like to know if anyone has found success using primarily or solely defense based champs in the areas I mentioned.

Yes. I use sustain/defense in arena and dungeon.  Gold4 and dragon20/golem20.

For dragon/golem. 1 poisoner (brawler 4 me) plus 4 sustain.  For me it was apothecary, gorgorab, zelotah and grizzled jarl I believe. 

Arena: zelotah (lead) gorgorab skullcrusher jarl 

Yes, defense based Arena team is a thing and those that are build with understanding are real pain to deal with.

But most of them are build around specific champ (Oh, hello Siphi! Nice to see you, Tormin!) or specific mechanic like CA, strong CC or just combination of big healh pool, shield set/s, stacked resistance and overall sustain, for example. Its not enough to just pick all your good defence based champions and call it "defence team".  There must be some basic idea you will build upon.  And its called that way not because you use defence based champions, but because of the concept itself. 

You have good champions for sure and you have some realy, really good one (and steady pull of dupes too:)), but I can't see combination that may work. If that was my roster, I will prefere speed team for Arena or some mix that will still rely on speed to set its defense/buffs up.
