>I was thinking about upgrade stations you could find inside dungeons to upgrade your mechasuit thing, with maybe light body horror sprinkled into it if I can find a good 3D artist to collaborate with
Not him but now that you mention that, I'm reminded of Stormlands, where you could apparently upgrade your body by ripping each limb off and popping a new one on. Such a shame they abandoned that game because Sony acquired them. 

Also btw if you're curious of VR roguelikes in general, there's Cosmodread, Dreadhalls, Compound, Ancient Dungeon VR, Until You Fall, and In Death. From Other Suns might also be interesting although its multiplayer I'm pretty sure is dead and it doesn't support SteamVR anyway so pirate and use Revive if you're interested
