It seems like a good idea. All i can think of though when i look at that picture is starbound.
It doesn't really fit with the theme Crimson/WhateverCountersit, I feel as though this just takes a far too futuristic and feels just a bit too synthetic and not natural enough to fit into Crimson/WhateverCountersit. If this was its own independent biome rather than a replacement to the Hallow, it would make much more sense and be a helluva lot more applicable.
Yeah, Greed would also make sense. Wrath makes more sense for the Destroyer, given the name, Sloth can probably be given to the Motherboard and then Gluttony to Prime.Maybe Might -> Wrath and Night -> Greed, but yeah.
Following that the mechs don't fit either. Cyber is basically a biome almost themed after them; if you don't like it then you should probably be complaining about the Mech bosses too.I'm possibly gonna be the only one here who thinks this but...
...i don't like it, IMO it doesn't fit terraria and from looking at the pictures, it looks more like something outta Starbound,
