(Reiteration of concept.)
Phase one
New modual, “Lead lining”. Prevents cargo and ship scans from being able to see into the cargo bay and ship load out. Ship looks like it has no cargo or moduals fitted.
Phase two
New modual, “False front array type 1” (Used in conjunction with “Lead lining”) Tricks ship scanners into seeing a different load out of moduals.
New modual, “False front array type 2” (Used in conjunction with “Lead lining”) Tricks cargo scanners into seeing a different cargo than what you actually have.
Phase 3
New modual, “Signature distortion” (Used in conjunction with “Lead lining”)
Makes the ship appear to be another ship on D-scan that has close to the same signature.
Phase 4
Introduction of the Q-ship
With it’s built in array of fun. 
That seem like a good development introduction?
