Vitality pet Ritualist with Corruptor of Spirits set?

I just finished Hardcore Elite with my lvl 80 vitality caster Ritualist

As you can see on the grimtools, I have found the full empowered Corruptor of Spirits set, which I have been using for its %vit damage and other stats.
Almost ready to move onto ultimate and I was wondering about the viability of switching to a Vitality pet build with this set. I have a few other pet-supporting items, such as the deadbeater which is also pet vitality damage.
If this was softcore I’d be happy to experiment myself, but this is the furthest I’ve ever got a HC character, I don’t have much iron and components in my HC stash and I don’t want to respec without figuring out if its viable first.
Vitality pets seems really interesting, especially cobined with devouring swarm and other RRs available to Ritualists. Has anyone ever run a similar build? Any info or advice would be appreciated. If not I will continue into ultimate as a caster.
Thanks!
