I figured I'd try my hand at making a "demonic washing machine", and came up with this:
The bottom teleporter has pressure plates that sends you back to the top, and activate the slime statues for the raven to chew on so you can get nebula armor buffs. (raven+mob statue idea shamelessly taken from blackshadowwind) This set up w/ nebula armor regens health faster than you loose it, so no heart statues needed. No heart statues mean you don't have to worry about hearts from enemies making the statues not work.
I tested this against 4 bosses at once (the three mechanical + golem) and took no damage from them. I even sat there for a while and half killed them with just star veil stars. Sadly, it does NOT work against the moon lord.
