Stealth & Crew Quality


I was thinking about stealth and crew quality.
Had thought, why have Stealth as CQ test instead, gives Elite and Veterans crew a better chance of spotting them and Green crew worse eg Sharlin would be Stealth 9, Miltary Crew needs a 5, Veteran a 4 and Elite a 3 to spot.
Would this not be a better way?
Thoughts anyone
