Honestly I find that the Borillo just by itself having stealth detection is as natural as giving Cthulhu cybernetics. The TD gets my vote with modifications that can grant stealth detection when inside a vehicle that holds two or more passengers such as the (Half-Track or Tsvil, etc) so it would limit it's expend-ability.
Nice analogy. I'm not sure that's possible with the engine though? I checked the Changelog anyway and it doesn't look like there are any changes regarding the stealth detection for the TD, and stealth detection has not been removed from the Borillo.
