Xenotypes

I'm trying to make a custom xenotype for a psychically powerful race of body modding weirdos.

I'm running the vanilla expanded race mods and alpha genes mods.

I'm having a spot of trouble with it. Has anyone made any cool xentoypes that go hand in hand with strong psycasters and transhumanists?

I was hoping to have them be quite durable, but I'm having a bit of a hard time making a solid build without having too many negatives.
