I think you are looking at creating Homebrew for this. I'm not seeing a way currently to add in these UA Variants. You might could create a Magic Item and duplicate the effect... but as it stands, either I'm missing it too or there is no way to add in things like Warlock Invocations currently in Home-brew. This is when people usually resort to creating items that can do this effect.
How do I add UA invocations to the list of options for my character sheet? Specifically, Gift of the Protectors.

We cannot edit or alter base class features such as Eldritch Invocations at this time. You could do it as a feat.
