That would be super easy. Just drop the elite lane logo on the BP before printing it, for the benefit of the line dragons.
On generating a bar code, I have decoded mine back in the day when it was the only way to find out if you have Pre-Check. There's a long character string after the PNR info, which I assumed was some type of encryption key. If true, I'd hope you'd need to regenerate the encryption key if you changed the PNR data.
