Ok, just a general reply, cause I’ll be busy for the half a day without access to my computer (I can reply this thread though).
I can share better images of the vehicle, but not that soon. I’ll probably just render it with a white texture, and use the opportunity to tilt piece 61800 at the front, even if that turns it from one illegal technique to another. The reason why there’s a lot of BS hiding of the vehicle is because it’s not the focus. That would be SpecterL’s beautiful Kanohi. Yes, I spent 7 continuous hours on the vehicle, including rendering, no iterations or refinement, which is less time than I spent on modelling out SpecterL’s Kanohi (link above for both).
Regarding making more vehicles, just no. It’s seriously not a priority, not even close to being a priority. Sure it would be nice to adapt SpecterL’s vehicle adaptive kanohi (pun intended) to 3D, but that’ll be incredibly time consuming, but my answer to you is not this year. I’ld rather remake Natetronimo/Big_Phan’s take on SpecterL’s take on the Mistika Kaukau, cause that’s probably easier than asking Natetronimo for permission to use in a game (though if you’ld like to ask on my behalf, be my guest). I’ld rather be playing SystemShock remake (which I bought but haven’t started) than make the vehicles, or even do more GWP style MOCs than make the vehicle, or even do my space garai or my regular Huna (my space Huna can be found Here). My main priority now is to remake the Hau and Akaku in my own style, with proper quad topology, cause making my own fan game is a long term goal I have (just be cautious more than optimistic, cause the only art I’ve worked on are the kanohi I’ve posted on the thingiverse).
And yeah, the mask is really cool, but it’s not my design. That’ll be SpecterL’s design. I’m simply the guy who 3D modelled it out… without permission (whoops). Just hope I don’t get cease & desist-ed.
Yeah, the name is just really really bad latin (and uninspired too). I swear I came up with a better name, then forgot about it… and now just remembered it… Was also considering calling it Eutrix or Eautrix (wesa doing a bad French). Should’ve gone with Praetrix instead, which is broken latin for female praetor/ praetorian guard. Oh well, I could always save that name for a female toa hagah not part of Norik’s hagah team (since the toa hagah are basically the praetorian guards of the high ranking makuta). And yes, I know Latin/ pseudo-latin is more of a spherus magna name than MU.
Edit: Don’t forget that Takanuva was the first of the Toa Nuva to get a vehicle, aka, the Ussanui. Now I think we can all agree an upgraded Ussanui would be good. Better yet, maybe it even interfaces with Gali’s vehicle, since both of them have a psychic bond (or perhaps even something more 
??? Basically Jaller’s fingers from that deleted scene in MOL, but instead it’s Av-Matoran Takua back when they were all in Karda Nui). I can remember if it was implied or explicitly states, but I’m sure the bond between Takua & Gali goes back to when the toa mata were still training under Hydraxon and the GSR hadn’t been fully completed.
