Bind demon plus Iron Golem

I am way behind on my warlock. Just finished Act 3 Normal, but I'm looking at the absolutely bonkers broken bind demons that people are coming up with and thought, "why not break it some more?"

Has anyone tried throwing on a

Metalgrid and summoing an

Iron Golem alongside your demons? Since you can already get a demon with extra strong, extra fast, cursed, spectral hit, immune to everything,

Conviction aura, extra

Gold find, extra magic find, extra experience, and gets your coffee for you affixes; and you can already hold a Insight and Spirit/Phoenix/

Tome at the same time, what would even be a good item to make the IG? Pride or Beast? Last Wish seems way too expensive. Can you make a Faith

Crossbow and then convert to IG?

Heard that

Iron Golem without Necromancer is kinda fragile.
