You are still risking the BCM won't recognize the HUD. The HUD interacts with the steering wheel controls and driving modes, get's it's data from the other car systems, etc. Somehow the car will need to be told that the HUD is there. I'd look into how that can be done before purchasing the parts.
There was a lengthy post in the C7 section of someone that attempted to add HUD to their car but I don't remember the outcome. See if you can find it for some guidance.

The forum member was able to install the HUD, but at the end of the day it required either replacing the upper dash or cutting up the existing dash and creating a frame to accommodate the projector. Replacing the upper dash was cost prohibitive and cutting up the dash did not have stock appearance. If the C8 HUD is like the C7 and C6 HUDs, there is no interface with the BCM.

All I really need now is photos of the disassembled dash to understand how the projector can be installed. There was a HVAC duct that needed to be cut to install the projector on the C6's. Hopefully the C8 is the same or better.

Not sure if this helps you or not, but it might.

Thanks for the photo. I am assuming this is a 1LT car.
