Depends on the feed protocols. Would be far easier to change the text and color displays, and have the headset send back an "override: incorrect identification" message back to the system. This "clears" the subject long enough for them to proceed and confuses, due to high levels of mismatch. Any system without such overrides would be non-functional, due to real world constraints.
Basic application of social engineering - find the most common override that shuts or delays the security and use that. Don't upgrade from BAD GUY to VIP, upgrade from BAD GUY to NORMAL or from NORMAL to VIP. Play the numbers.
(caveat: none of this will impact real world risks, which are already set up for failure)
